[PATCH] net/enic: avoid extra unlock when setting MTU in enic

[Weiguo Li <liwg06@foxmail.com>]

The 'set_mtu_done' goto statement is being executed in a context
where the 'mtu_lock' has not been previously locked.

To avoid the extra unlocking operation, replace the goto statement
with a return statement.
