scsi: ufs: core: Unbreak the reset handler
[ Upstream commit d04a968c33684b15d1206e23fc1119ce0f0587fb ]
A command tag is passed as the second argument of the
__ufshcd_transfer_req_compl() call in ufshcd_eh_device_reset_handler()
instead of a bitmask. Fix this by passing a bitmask as argument instead of
a command tag.
