Revert the cargo-culted changes to sata_request.

This reverts commit ffd36865cf3e66a57f5b1c5e938d53bdbd1c9933.

They didn't fix anything, and on some systems it's reported that they
cause boot failures.

Fixes #14272.

sata_request: Cargo-cult some behaviors from FreeBSD.

See 13778#comment:3 for information on FreeBSD behaviors.

I didn't manage to locate where the specification talks about this
(but my specification-fu is rather poor), and it didn't fix the check_sense
syslog spamming on my machine.

But it seems to continue to function as before on my hardware as well as
VirtualBox and VMware, so perhaps it might fix something else.

ahci: Minor coding style cleanup.

* Renamed some methods to camel case.
* Replaced coding error panics with ASSERTs.

ahci: fixed endless loop, and missing bit.

* The value for trim is bit 0, not 0; added sata_request::SetFeature()
to change this.
* The lba range fill loop never ended.
* Thanks to Marcus for proof-reading!

ahci: fixed typo and narrowing conversion warning.

* completition -> completion.

* Call PostReset() at the end of ResetPort() as it's always used in that way.
* Reset the port directly after executing a command failed instead of letting
the next call do the reset first. This is arbitrary but looks cleaner to me.
* Provide a way to check if a given sata_request is a SCSI_OP_TEST_UNIT_READY
over ATAPI and use this info to calm down all error output. This avoids
spamming the syslog with error output on each media status poll when no disk
is present in a ATAPI device.

Set transfer length when doing ATAPI transfers.
Dump ATAPI command packet on error.

The AHCI controller doesn't natively support ATAPI commands.
Instead, one needs to execute the ATA command 0xa0 (PACKET) using
a normal ATA PIO FIS and in addition fill the SCSI CDB into the ACMD
space to transfer the ATAPI PACKET command.

More preparation for sending ATAPI PACKET commands (pass through of SCSI commands).

A helper class to easier support Native Command Qeueuing and ATAPI support.
This class either encapsulates scsi_ccb or can be used stand alone.
