staging: wfx: check for memory allocation failures from wfx_alloc_hif
Currently calls to wfx_alloc_hif are not checking for a null return when a memory allocation fails and this leads to null pointer dereferencing issues. Fix this by adding null pointer checks and returning passing down -ENOMEM errors where necessary. The error checking in the current driver is a bit sparse, so this may need some extra attention later if required.
