UPSTREAM: scsi: ufs: core: Remove redundant HPB unmap

Browse Source 
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 also resolves the issue where HPB WRITE BUFFER is issued before UAC is
cleared.
