[PATCH] proc: proc_get_inode should de_put when inode already initialized

[Krzysztof Sachanowicz]

de_get is called before every proc_get_inode, but corresponding de_put is 
called only when dropping last reference to an inode. This might cause 
something like
remove_proc_entry: /proc/stats busy, count=14496
to be printed to the syslog.

The fix is to call de_put in case of an already initialized inode in 
proc_get_inode.
