posix: Ensure EINVAL return on NULL args
Initing op_errno to EINVAL ensures that this is the value that gets returned on STACK_UNWIND, in case any of the VALIDATE macros result in exit from "out" due to a NULL argument. If this is not done , we get op_ret as -1 with errno set to 0 in the application's syscall. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
