[PATCH 1/1] scsi: ufs: remove redundant HPB unmap

[Po-Wen Kao]

Since the HPB mapping is already reset in ufshpb_init by setting
flag QUERY_FLAG_IDN_HPB_RESET, there is no need doing so again in
ufshpb_hpb_lu_prepared.

This would also resolve the issue where HPB WRTIE BUFFER is issued
before UAC being cleared.
