staging: xillybus: Return -EIO if *_iomap fails, instead of 0



This patch replicates the correction made by Wei Yongjun on a second
occurrence of the same bug.

The first correction was in commit 8eec4555.

Bug fixed: The error code was not set, so the error condition wasn't reflected
in the return value.
