From: Alan Stern <stern@rowland.harvard.edu>

This patch (as960) removes the error message and stack dump logged by
sysfs_remove_bin_file() when someone tries to remove a nonexistent file. 
The warning doesn't seem to be needed, since none of the other file-,
symlink-, or directory-removal routines in sysfs complain in a comparable
way.
