USB: storage: Use normalized sense when emulating autosense
commit e16da02fcdf1c5e824432f88abf42623dafdf191 upstream.
This patch solves two things:
1) Enables autosense emulation code to correctly
interpret descriptor format sense data, and
2) Fixes a bug whereby the autosense emulation
code would overwrite descriptor format sense data
with SENSE KEY HARDWARE ERROR in fixed format, to
incorrectly look like this:
