Log Message:
separate ata_xfer slot allocation and the memory allocation, so that
there can be more queued xfers than number of supported slots by controller,
and use a pool instead of custom pre-allocation

primarily to help PR kern/52614

remove no longer needed custom wd(4) logic for flush cache

switch also wd(4) trim/suspend/setcache/wdioctlstrategy to sleep waiting
for the memory, they are all called from process context and this
avoids spurious failures
