drm/amd/display: Fix dangling pointer in plane reset function
amdgpu_dm_plane_drm_plane_reset() frees the old state before allocating
a new one. If kzalloc() fails, the function returns without updating
the state pointer, leaving a dangling pointer to already freed memory.
Fix this by allocating the new state first. On allocation failure, the
old state remains untouched and the function safely returns.
