dblksize warning

[Matthew Dillon]

:While cleaning up warnings in sbin/dump I noticed that the dblksize
:macro was emitting a warning.  I'm not a fs expert, so I'm not sure
:what the appropriate fix is, but the attached patch seems to work.

:Thoughts?

    Those macros are a bit weird.  The implied type is often based on the
    type of the element passed to the macro so I am not at all sure that
    it is a good idea to cast fs_bsize.  I'm inclined to allow the warning
    to stay intact for the moment.
