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

[Piro Yang]

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

Replace -ENOSYS error code by returning -EINVAL error code

Please wrap your changelog text at 72 columns, like your editor asked
you to.

And use '.' as these are real sentences, right?

And some ' ' in the subject line, like:
	staging: vme_user: Fix...

Usually writing the changelog and getting it correct is the hardest part
of getting a change accepted.

thanks,
