[PATCH V3 RESEND] staging:vme_user:Fix the issue of return the wrong error code

[Piro Yang]

Fixed 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 using -EINVAL error code to return.
