Mark Johnston 725962a9f4 e6000sw: Fix locking in miibus_{read,write}reg implementations ...

Commit 4692906480 made e6000sw's
implementation of miibus_(read|write)reg assume that the softc lock is
held.  I presume that is to avoid lock recursion in e6000sw_attach() ->
e6000sw_attach_miibus() -> mii_attach() -> MIIBUS_READREG().

However, the lock assertion in e6000sw_readphy_locked() can fail if a
different driver uses the interface to probe registers.  Work around the
problem by providing implementations which lock the softc if it is not
already locked.
