Silence warnings about possible uninitialize use of dst_format.
Whoa, gcc got a lot smarter about warnings. If iXXX_get_dest_format()
doesn't support the picture format passed in it won't initialize the
uint32_t pointed to by dst_format and return FALSE.
What gcc now can detect is if dst_format is used without checking the
return value, it might be used uninitialized. This patch makes sure
we always check the return value before using dst_format.
