drm/tgm: fix deadlock issue

Fixed a deadlock issue on mem_lock of tdm pp driver.

The deadlock could happen when pp_start_property function
is called at the funciton which already taken a mem_lock
because pp_start_property takes the mem_lock internally
so this patch makes the mem_lock to be unlocked before
pp_start_property funciton is called.
