gprs: Add assertion for msg != NULL to bssgp_msgb_alloc (Coverity)
Currently out-of-memory is not handled by bssgp_msgb_alloc, leading
to SEGV failures if msgb_alloc_headroom returns NULL.
This commit adds an OSMO_ASSERT to catch this case, which improves
the situation only slightly. But bssgp_msgb_alloc is used in many
places without checking the return value, so just adding a
conditional early NULL return would not fix the issue either.
Fixes: Coverity CID 1293377

msgb: Check the return value of msgb_alloc (Coverity)
In some places, the return value of msgb_alloc/msgb_alloc_headroom
is not checked before it is dereferenced.
This commit adds NULL checks to return with -ENOMEM from the calling
functions if the alloc function has failed.
