parentgeneric_acl: no need to clone acl just to push it to set_cached_acl() (diff)

kill boilerplates around posix_acl_create_masq()
new helper: posix_acl_create(&acl, gfp, mode_p). Replaces acl with modified clone, on failure releases acl and replaces with NULL. Returns 0 or -ve on error. All callers of posix_acl_create_masq() switched. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
