kgdb: initialize n_type field of nlist entry for kvm_nlist call

Browse Source 
kvm_nlist skips lookup for entries that have n_type != N_UNDF.
N_UNDF happens to be zero, so n_type typically has a correct
value by accident, but not always.
Note: jhb has a patch that replaces kvm_nlist use with direct
gdb parsing.

MFC after:	5 days
X-MFC-Note:	unless jhb commits kvm_nlist => kgdb_parse change
