scsi: ufs: fix static checker warning in ufshcd_parse_clock_info

This patch fixes newly introduced static checker warning in
ufshcd_parse_clock_info, introduced by UFS power management series.

Warning:
drivers/scsi/ufs/ufshcd-pltfrm.c:138 ufshcd_parse_clock_info()
warn: passing devm_ allocated variable to kfree. 'clkfreq'

To fix it we remove the kfree(clkfreq) statement.
In addition we removed the redundant goto label.
