USB: storage: Use normalized sense when emulating autosense

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:

Oct 21 14:11:07 localhost kernel: sd 7:0:0:0: [sdc]  Sense Key : Recovered Error [current] [descriptor]
Oct 21 14:11:07 localhost kernel: Descriptor sense data with sense descriptors (in hex):
Oct 21 14:11:07 localhost kernel:        72 01 04 1d 00 00 00 0e 09 0c 00 00 00 00 00 00
Oct 21 14:11:07 localhost kernel:        00 4f 00 c2 00 50
Oct 21 14:11:07 localhost kernel: sd 7:0:0:0: [sdc]  ASC=0x4 ASCQ=0x1d
