s5p-mfc: Fix clock management in s5p_mfc_release() function
commit c0026c7bfb95c250c3e34fde59f96ad72fd730d6 upstream.
Clock control indirectly requires access to MFC device, so call it only
if we are sure that the device exists in s5p_mfc_release function.
s5p_mfc_remove() calls s5p_mfc_final_pm(), which releases all PM related
resources, including clocks, so any call to clocks related functions
is not valid after s5p_mfc_final_pm().
Fixes: d695c12 ("[media] media: s5p-mfc fix invalid memory access from
s5p_mfc_release()")
