When the root filesystem is mounted, the iwm(4) driver will try to
load firmware from the root filesystem in order to read the MAC
address.
This has never worked in bsd.rd and results in a bogus "could not
load firmware" error being displayed during every upgrade.
With this diff, when the driver runs in bsd.rd it will try to
load firmware when the interface comes up for the first time
which avoids the pointless error.
Personally, I think this change is long overdue...
