Subject: [PATCH] sysfs: don't warn on removal of a nonexistent binary file

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.

This is 2.6.23 material.  The spurious error message can be triggered
by USB code added since 2.6.22, so it needs to be removed before the 
final release.
