Daniel Gomez 67e06e8a77 netfilter: replace -EEXIST with -EBUSY 
[ Upstream commit 2bafeb8d2f ]

The -EEXIST error code is reserved by the module loading infrastructure
to indicate that a module is already loaded. When a module's init
function returns -EEXIST, userspace tools like kmod interpret this as
"module already loaded" and treat the operation as successful, returning
0 to the user even though the module initialization actually failed.

Replace -EEXIST with -EBUSY to ensure correct error reporting in the module
initialization path.

Affected modules:
  * ebtable_broute ebtable_filter ebtable_nat arptable_filter
  * ip6table_filter ip6table_mangle ip6table_nat ip6table_raw
  * ip6table_security iptable_filter iptable_mangle iptable_nat
  * iptable_raw iptable_security
