Steffen Maier d4316c155c lszfcp: save a stat syscall on the SCSI device loop hot path ...

Just go ahead and read the sysfs attribute directly as the syscalls are
needed anyway.
If necessary stderr could be redirected to /dev/null in the future,
but there was no case so far where the attribute did not exist.

This does not make a runtime difference when running on sysfs. Change it
anyway to avoid somebody searching for speed improvement options stumbling
over it again.
