media: ti-vpe: vpe: fix a v4l2-compliance warning about invalid pixel format
v4l2-compliance warns with this message:
warn: v4l2-test-formats.cpp(717): \
TRY_FMT cannot handle an invalid pixelformat.
warn: v4l2-test-formats.cpp(718): \
This may or may not be a problem. For more information see:
warn: v4l2-test-formats.cpp(719): \

...
test VIDIOC_TRY_FMT: FAIL
We need to make sure that the returns a valid pixel format in all
instance. Based on the v4l2 framework convention drivers must return a
valid pixel format when the requested pixel format is either invalid or
not supported.
