scsi: ufs: Fix toggling of clk_gating.state when clock gating is not allowed

This commit addresses an issue where clk_gating.state is being toggled in
ufshcd_setup_clocks() even if clock gating is not allowed.

The fix is to add a check for hba->clk_gating.is_initialized before toggling
clk_gating.state in ufshcd_setup_clocks().

Since clk_gating.lock is now initialized unconditionally, it can no longer
lead to the spinlock being used before it is properly initialized, but
instead it is mostly for documentation purposes.
