scsi: ufs: qcom: Avoid re-init quirk when gears match

On sa8775p-ride, probing the HBA will go through the
UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH path although the power info is
the same during the second init.

The REINIT quirk only applies starting with controller v4. For these,
ufs_qcom_get_hs_gear() reads the highest supported gear when setting the
host_params. After the negotiation, if the host and device are on the same
gear, it is the highest gear supported between the two. Skip REINIT to save
some time.
