streamline init/exit path

Currently the xfs module init/exit code is a mess.  It's farmed out
over a lot of function with very little error checking.  This patch
makes sure we propagate all initialization failures properly and clean
up after them.  Various runtime initializations are replaced with
compile-time initializations where possible to make this easier.  The
exit path is similarly consolidated.

There's now split out function to create/destroy the kmem zones and
alloc/free the trace buffers.  I've also changed the ktrace
allocations to KM_MAYFAIL and handled errors resulting from that.

And yes, we really should replace the XFS_*_TRACE ifdefs with a single
XFS_TRACE..
