[PATCH] netfilter: nf_tables: remove redundant assignment of variable err

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variable err is being assigned a value that is never read,
the same error number is being returned at the error return
path via label err1.  Clean up the code by removing the assignment.

Addresses-Coverity: ("Unused value")
