Denis V. Lunev c4185a0e01 proc: proc_get_inode() should get module only once
Any file under /proc/net opened more than once leaked the refcounter
on the module it belongs to.

The problem is that module_get is called for each file opening while
module_put is called only when /proc inode is destroyed. So, lets put
module counter if we are dealing with already initialised inode.
