        sys/dev/scsipi/scsiconf.c: revision 1.263
        sys/dev/scsipi/scsiconf.c: revision 1.264
        sys/dev/ic/ncr53c9x.c: revision 1.144
        sys/dev/ic/ninjascsi32.c: revision 1.22
        sys/dev/usb/uhub.c: revision 1.117
take the kernel lock in functions called from attach*().
scsidevdetached ioctl path enters scsipi code without kernel lock
and this upsets the newer kasserts.  take kernel lock here.
take the kernel lock a few more places when doing detach, to avoid
triggering KERNEL_LOCK_P() asserts in both scsi and usb code.
with this and other recent fixes i can now "drvctl -d ehci0".
