Colin Ian King f0dfd7a2b3 netfilter: nf_tables: fix memory leak on error exit return 
Currently the -EBUSY error return path is not free'ing resources
allocated earlier, leaving a memory leak. Fix this by exiting via the
error exit label err5 that performs the necessary resource clean
up.

Detected by CoverityScan, CID#1432975 ("Resource leak")

Fixes: 9744a6fcef ("netfilter: nf_tables: check if same extensions are set when adding elements")
