Icenowy Zheng ecd4e93456 pvr: add deferred RTA clear command to list after checking it's not NULL
The code that adds deferred RTA clear transfer commands checks whether
the newly allocated transfer command is NULL. However the list_addtail
call is before the check, which means that the check does not prevent
NULL dereference.

Reorder the code to ensure no NULL transfer commands would ever be added
to the deferred clear list.

In addition, pvr_transfer_cmd_alloc() has already set the command
buffer's error status when it returns NULL, so it's not needed to set it
again.
