[PATCH v4 4/4] scsi: ufs: core: Always initialize the UIC done completion

[Bart Van Assche <bvanassche@xxxxxxx>]

Simplify __ufshcd_send_uic_cmd() by always initializing the
uic_cmd::done completion. This is fine since the time required to
initialize a completion is small compared to the time required to
process an UIC command.
