Subject: tipc: check return value of nlmsg_new
From: Pan Bian <bianpan2016@xxxxxxx>
[ Upstream commit 78302fd405769c9a9379e9adda119d533dce2eed ]
Function nlmsg_new() will return a NULL pointer if there is no enough
memory, and its return value should be checked before it is used.
However, in function tipc_nl_node_get_monitor(), the validation of the
return value of function nlmsg_new() is missed. This patch fixes the
bug.
