iavf: Remove queue tracking fields from iavf_adminq_ring

Fields 'head', 'tail', 'len', 'bah' and 'bal' in iavf_adminq_ring
are used to store register offsets. These offsets are initialized
and remains constant so there is no need to store them in the
iavf_adminq_ring structure.

Remove these fields from iavf_adminq_ring and use register offset
constants instead. Remove iavf_adminq_init_regs() that originally
stores these constants into these fields.

Finally improve iavf_check_asq_alive() that assumes that
non-zero value of hw->aq.asq.len indicates fully initialized
AdminQ send queue. Replace it by check for non-zero value
of field hw->aq.asq.count that is non-zero when the sending
queue is initialized and is zeroed during shutdown of
the queue.

intel-ethernet: clean up W=1 warnings in kdoc

This takes care of all of the trivial W=1 fixes in the Intel
Ethernet drivers, which allows developers and maintainers to
build more of the networking tree with more complete warning
checks.

There are three classes of kdoc warnings fixed:
- cannot understand function prototype: 'x'
- Excess function parameter 'x' description in 'y'
- Function parameter or member 'x' not described in 'y'

All of the changes were trivial comment updates on
function headers.

Inspired by Lee Jones' series of wireless work to do the same.
Compile tested only, and passes simple test of
$ git ls-files *.[ch] | egrep drivers/net/ethernet/intel | \
xargs scripts/kernel-doc -none

iavf: change remaining i40e defines to be iavf

There were a couple of erroneously missed i40e names to
update to iavf left after the larger chunks. Updated them
separately so now they should all be aligned as iavf.

be iavf as well.
