mm: madvise(): correct return code
The posix_madvise() function succeeds (and does nothing) when called with
parameters (NULL, 0, -1); according to LSB tests, it should fail with
EINVAL because -1 is not a valid flag.
When called with a valid address and size, it correctly fails.
So perform an initial check for valid flags first.
