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. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=10737 Signed-off-by: Denis V.
