Log Message:
do not do the drive reset on non-fatal recovery - spec explicitely says
says the READ LOG EXT should only be done when neither COMRESET nor software
reset was done, and indeed it returns junk in this case

use C_RECOVERY slot for drive reset, so that it now will always succeed
in getting a slot, in cases when it would be necessary

adjust code and comments on the recovery path to explain better what's going on

with this AHCI error recovery works with real hardware without timeouts again
