kernel/mfi: Move the dereference of 'sc' below the NULL check.

kernel: Use DEVMETHOD_END in the drivers.

mfi(4): Add D_MPSAFE to the disk flags.

When porting it, I didn't know that this is indicated by the _absence_
of DISKFLAG_NEEDSGIANT.

mfi(4): Don't assert lock holding when dumping or during a panic.

FreeBSD's mtx_assert() does it the same way, but we usually translate
mtx_assert() into a KKASSERT(lockstatus(&lock, curthread) != 0

mfi(4): Don't assert lock holding when dumping or during a panic.

FreeBSD's mtx_assert() does it the same way, but we usually translate
mtx_assert() into a KKASSERT(lockstatus(&lock, curthread) != 0).

For now, replace all of these assertions in mfi(4) with a function that
mimics the mtx_assert() behavior of FreeBSD, since some of the asserting
functions are used by the dumping code.

We might think about a real lockassert() function in the future that
has this exception too.

This commit fixes dumping on most supported adapters. Thunderbolt series
adapters still have an (unrelated) command timeout issue which I'm
looking at.

Reported and tested (on a PERC 5/i) by Tim Howe <tim@130collective.org>.

mfi(4): Update to LSI's version 4.23 of the driver.

Brings in support for newer SAS2208 (aka Thunderbolt) based
controllers. It was tested with an Intel RS25DB080.

A few other things have been fixe

A few other things have been fixed too. Most x86_64/i386 specific
parts have been merged, MSI is now setup in mfi_pci.c properly.

kernel: Use NULL for DRIVER_MODULE()'s evh & arg (which are pointers).

This is just cosmetics for easier reading.
