Log Message:
Return error if we try to mount a file system with block size > MAXBSIZE.
Note: there is a billion ways to make the kernel panic by trying
to mount a garbage file system and I don't imagine we'll ever get
close to fixing even half of them. However, for this one failing
gracefully is a bonus since Xen DomU only does 32k MAXBSIZE and
the 64k MAXBSIZE file systems are out there (PR port-xen/43727).
Tested by compiling sys/rump with CPPFLAGS+=-DMAXPHYS=32768 (all
tests in tests/fs still pass). I don't know how we're going to
translate this into an easy regression test, though. Maybe with
a hacked newfs?
