Subject: [PATCH] net/enic: avoid extra unlock when setting MTU in enic
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.
Fixes: c3e09182bcd6 ("net/enic: support scatter Rx in MTU update")
