b43: only reload config after successful initialization
commit dbdedbdf4fbff3d4962a0786f37aa86dfdc48a7e upstream.
Commit 2a19032 (b43: reload phy and bss settings after core restarts)
introduced an unconditional call to b43_op_config() at the end of
b43_op_start(). When firmware fails to load this can wedge the system.
There's no need to reload the configuration after a failed
initialization anyway, so only make the call if initialization was
successful.
