[PATCH] bus: mhi: host: Use ERANGE for BHIOFF/BHIEOFF range check

[Jeffrey Hugo]

If the BHIOFF or BHIEOFF range checks fail, they return EINVAL.  ERANGE
is a better error code since it implies an out of range condition.

This feels more like a style change than fixing a bug, so I'm being
conservative and intentionally not listing a fixes tag.
