[PATCH] nvme: use DEFINE_SIMPLE_SYSFS_GROUP_VISIBLE for multipath_sysfs

[John Garry]

Use DEFINE_SIMPLE_SYSFS_GROUP_VISIBLE instead of
DEFINE_SYSFS_GROUP_VISIBLE, which means that we can drop
multipath_sysfs_attr_visible().

Incidentally, multipath_sysfs_attr_visible() should have returned a
umode_t.

This idea was suggested by Ben Marzinski elsewhere.
