BACKPORT: FROMLIST: scsi: ufs: Export query request interfaces

Vendor drivers may need to send query requests in vendor specific
implementations. Hence, export the query request interfaces so that
vendor drivers can use them.

Removed export of internal helper functions:
ufshcd_query_attr_retry() and ufshcd_query_flag_retry().
