Colin Ian King a61ecd329c apparmor: fix error returns checks by making size a ssize_t ...

Currently variable size is a unsigned size_t, hence comparisons to
see if it is less than zero (for error checking) will always be
false.  Fix this by making size a ssize_t

Detected by CoverityScan, CID#1466080 ("Unsigned compared against 0")

Fixes: 8e51f9087f ("apparmor: Add support for attaching profiles via xattr, presence and value")
