sysfs: remove useless test from sysfs_merge_group
Dan Carpenter pointed out that the new sysfs_merge_group() and
sysfs_unmerge_group() routines requires their grp argument to be
non-NULL, because they dereference grp to obtain the list of
attributes. Hence it's pointless for the routines to include a test
and special-case handling for when grp is NULL. This patch (as1433)
removes the unneeded tests.
