Re: [PATCH] xfsprogs: fix up the noreturn annotations

[Christoph Hellwig <hch@xxxxxxxxxxxxx>]

The usage function in mkfs needs a noreturn annotation too, otherwise
gcc will complain, similarly the do_msg function in repair would need
it if do_abort is set, but because conditional annotations aren't
possible just clean this area up an inline the do_msg function into
it's callers.
