[USBSTOR] Rework the routines for sending internal SCSI requests.
Now for each request SenseBuffer is correctly set
and 3 attempts are made to be sure the STALL state is cleared and
the error is in something else.
Remove the usage of UFI_INQUIRY_DATA structure in favor of "standard"
INQUIRYDATA structure from scsi.h
Based in Vadim Galyant's patches to usbstor
