kfree() has no problems dealing with NULL pointers, so wrapping checks for
null round calls to it is redundant. This patch gets rid of two such
checks in net/ipv6/ip6_flowlabel.c
I considered also rewriting the
if (fl)
fl_free(fl);
bit as simply fl_free(fl) as well, but that if() potentially saves two
calls to kfree() inside fl_free as well as the call to fl_free itself, so
I guess that's worth the if().
Please consider applying.
