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.
