media: meson: add missing allocation failure check on new_buf
Currently if the allocation of new_buf fails then a null pointer
dereference occurs when assiging new_buf->vb. Avoid this by returning
early on a memory allocation failure as there is not much more can
be done at this point.
Addresses-Coverity: ("Dereference null return")
Fixes: 3e7f51bd9607 ("media: meson: add v4l2 m2m video decoder driver")
