[POWERPC] spufs: Don't leak kernel stack through an empty {i,m}box_info read
Based on an original patch from Arnd Bergmann
<arnd.bergmann@de.ibm.com>
If there's no entry in the mailbox, then a read on the _info file will
return data from an uninitialised variable.
This change returns EOF if there's no mailbox info available instead.
