xfstests: print the message that fallocate is not supported to stdout unless quiet output

[Boris Ranto]

ltp/fsx.c tests whether the filesystem it is run on supports fallocate. If it is not supported the fsx will print warning to stderr.
This leads to fails of tests 075, 112, 127 for the filesystems that do not support fallocate. The tests use ltp/fsx but do not filter out stderr.
Since ltp/fsx.c can work without fallocate support I propose to move this message to stdout unless quiet output is not requested.
Previous patch printed the message even if -q flag was used. This patch honours the flag.

This simple patch fixes the issue for me, tested on all the mentioned tests:
