file-posix: allow -EBUSY errors during write zeros on raw block devices
On Linux, fallocate(fd, FALLOC_FL_PUNCH_HOLE) when it is used on a block device,
without O_DIRECT can return -EBUSY if it races with another write to the same page.
Since this is rare and discard is not a critical operation, ignore this error
