Subject: [PATCH 13/13] scsi: ufs: qcom: Initialize cycles_in_1us variable in ufs_qcom_set_core_clk_ctrl()

In case the "core_clk_unipro" clock is not provided, "cycles_in_1us"
variable will be used as uninitialized. So initialize it with 0.

Issue reported by Smatch tool:

drivers/ufs/host/ufs-qcom.c:1336 ufs_qcom_set_core_clk_ctrl() error: uninitialized symbol 'cycles_in_1us'.
drivers/ufs/host/ufs-qcom.c:1341 ufs_qcom_set_core_clk_ctrl() error: uninitialized symbol 'cycles_in_1us'.
