common: Make openpgp_oid_to_str more robust.
* common/openpgp-oid.c (openpgp_oid_to_str): Take care of
gcry_mpi_get_opaque returning NULL. Remove useless condition !BUF.
--
It is possible that an opaque MPI stores just a NULL pointer. Take
care of that before incrementing the pointer. We return an error in
this case because at least a length byte is required.
Found due to hint from stack 0.3:
