mtip32xx: fix up the checking for internal command failure
This fixes up two commits that have touched this driver. The
command status field is now a blk_status_t, so we can't check
for < 0 and we definitely can't assume it's holding -Exxxx error
values. All we care about here is whether ->status is zero or not.
Check for that, and remove the various attempts at smart error
reporting. Just log to dmesg what command failed, and the
blk_status_t value.

Fixes: 2a842acab109 ("block: introduce new block status code type")
Fixes: 3f5e6a35774c ("mtip32xx: convert internal command issue to block IO path")
