keys: fix sparse warning by adding __user annotation to cast
Fix the following sparse warning:
CC security/keys/key.o
security/keys/keyctl.c:1297:10: warning: incorrect type in argument 2 (different address spaces)
security/keys/keyctl.c:1297:10: expected char [noderef] <asn:1>*buffer
security/keys/keyctl.c:1297:10: got char *<noident>
which appears to be caused by lack of __user annotation to the cast of
a syscall argument.
