scsi: ufs: ufs-qcom: Remove unneeded code
Checks information about tx_lanes, but is not used. Since commit 1e1e465c6d23 ("scsi/ufs: qcom: Remove ufs_qcom_phy_*() calls from host"), tx_lanes is deprecated. As a result, ufs_qcom_link_startup_notify -> POST_CHANGE action does nothing. If it is not going to be updated, it can be removed.
