staging: vme_user: Fix the issue of return the wrong error code

Fix the issue of returning the -ENOSYS error code when an error occurs.

The error code of -ENOSYS indicates Invalid system call number, but
there is not system call error. So replace -ENOSYS error code by the
return -EINVAL error code.
