9pfs double kfree

[Dave Jones <davej@redhat.com>]

Probably the first of many found with Coverity.

This is kfree'd outside of both arms of the if condition already,
so fall through and free it just once.

Second variant is double-nasty, it deref's the free'd fcall
before it tries to free it a second time.

(I wish we had a kfree variant that NULL'd the target when it was free'd)

Coverity bugs: 987, 986
