The hpsa driver uses this function to cleanup inquiry
data. Our new pqi driver will also use this
function. This function was copied into both drivers.
This patch exports sanitize_inquiry_string so the hpsa
and the pqi drivers can use this function directly.
Hannes recommended the change in review:
https://www.marc.info/?l=linux-scsi&m=144619249003064&w=2
that using the existing function in scsi_scan would be
preferrable.
Matthew R. Ochs also recommended the change in review:

Changes from initial upload:
- Added prototype for sanitize_inquiry_string to scsi_device.h
