qsvdec: Pass the correct profile to libmfx

Browse Source 
This was correct for H.26[45], because libmfx uses the same values
derived from profile_idc and the constraint_set flags, but it is
wrong for other codecs.

Also avoid passing FF_LEVEL_UNKNOWN (-99) as the level, as this is
certainly invalid.
