scsi: ufs: host: mediatek: Fix invalid access in vccqx handling

Browse source

[ Upstream commit 5863638598 ]

Add a NULL check before accessing the 'vccqx' pointer to prevent invalid
memory access. This ensures that the function safely handles cases where
'vccq' and 'vccq2' are not initialized, improving the robustness of the
power management code.
