tipc: fix variable dereference before NULL check
In commit cf6f7e1d5109 ("tipc: dump monitor attributes"),
I dereferenced a pointer before checking if its valid.
This is reported by static check Smatch as:
net/tipc/monitor.c:733 tipc_nl_add_monitor_peer()
warn: variable dereferenced before check 'mon' (see line 731)
In this commit, we check for a valid monitor before proceeding
with any other operation.
Fixes: cf6f7e1d5109 ("tipc: dump monitor attributes")
