[PATCH] rtlwifi: remove redundant assignment to variable err

From: Colin King <hidden>
Date: 2021-03-27 23:01:10

From: Colin Ian King <redacted>

Variable err is assigned -ENODEV followed by an error return path
via label error_out that does not access the variable and returns
with the -ENODEV error return code. The assignment to err is
redundant and can be removed.
