MFC r297527, r297688: chdone(): Prevent returning uninitialized scalar value.
Instead of attempting to initialize all the possible cases, just move the check nearer to the case where it makes sense.

MFC Alexander Motin's direct dispatch, multi-queue, and finer-grained locking support for CAM
r256826: Fix several target mode SIMs to not blindly clear ccb_h.flags field of ATIO CCBs. Not all CCB flags there belong to them.
r256836: Remove hard limit on number of BIOs handled with one ATA TRIM request.
r256843: Merge CAM locking changes from the projects/camlock branch to radically reduce lock congestion and improve SMP scalability of the SCSI/ATA stack, preparing the ground for the coming next GEOM direct dispatch support.
r256888: Unconditionally acquire periph reference on CCB allocation failure.
r256895: Fix memory and references leak due to unfreed path.
r256960: Move CAM_UNQUEUED_INDEX setting to the last moment and under the periph lock. This fixes race condition with cam_periph_ccbwait(), causing use-after-free.
r256975: Minor (mostly cosmetical) addition to r256960.
r257054: Some microoptimizations for da and ada drivers: - Replace ordered_tag_count counter with single flag; - From da remove outstanding_cmds counter, duplicating pending_ccbs list; - From da_softc remove unused links field.
r257482: Fix lock recursion, triggered by `smartctl -a /dev/adaX`.
r257501: Make getenv_*() functions and respectively TUNABLE_*_FETCH() macros not allocate memory and so not require sleepable environment. getenv() has already used on-stack temporary storage, so just use it more rationally. getenv_string() receives buffer as argument, so don't need another one.
r257914: Some CAM locks polishing: - Fix LOR and possible lock recursion when handling high-power commands. Introduce new lock to protect left power quota and list of frozen devices. - Correct locking around xpt periph creation. - Remove seems never used XPT_FLAG_OPEN xpt periph flag.
Again, Netflix assisted with testing the merge, but all of the credit goes to Alexander and iX Systems.
