[PATCH][next] apparmor: remove useless static inline function is_deleted

[PATCH][next] apparmor: remove useless static inline function is_deleted

[Colin Ian King]

The inlined function is_deleted is redundant, it is not called at all
from any function in security/apparmor/file.c and so it can be removed.

Cleans up clang scan build warning:
security/apparmor/file.c:153:20: warning: unused function
'is_deleted' [-Wunused-function]
