netlink: add NULL check for get_string() in features.c
Report of the static analyzer:
Return value of a function 'get_string' is dereferenced at features.c:279
without checking for NULL, but it is usually checked for this function (6/7).
Correct explained:
Added NULL check for get_string() return value before passing to strcmp()
to prevent potential NULL pointer dereference. This matches the behavior
in other similar code paths where get_string() is used.
