[Libguestfs] Coverity: possible false positive in debug_qtrace

[Richard W.M. Jones]

http://git.annexia.org/?p=libguestfs.git;a=blob;f=daemon/debug.c;h=cd3e8a5f0294a910782b38552d2b0757869f862c;hb=HEAD#l430

Coverity complains about the error path from posix_memalign (lines
477-482) saying that 'buf' will be leaked.

However my reading of the posix_memalign man page is that if the
return value from posix_memalign != 0 then 'buf' would not have been
allocated.
