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

Vendor drivers may need to send query requests in proprietary
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
