staging: vme_user: added bound check to geoid
[ Upstream commit a8a8b54350229f59c8ba6496fb5689a1632a59be ]
The geoid is a module parameter that allows users to hardcode the slot number.
A bound check for geoid was added in the probe function because only values
between 0 and less than VME_MAX_SLOT are valid.
