usb: atm: Remove snprintf() from sysfs call-backs and replace with sysfs_emit()
Since snprintf() has the documented, but still rather strange trait of
returning the length of the data that *would have been* written to the
array if space were available, rather than the arguably more useful
length of data *actually* written, it is usually considered wise to use
something else instead in order to avoid confusion.
In the case of sysfs call-backs, new wrappers exist that do just that.
This patch replaces the 2 uses of snprintf() found in the sysfs .show()
call-backs with the new sysfs_emit() helpers. Whist we're at it, let's
replace the sprintf()s as well. For no other reason than consistency.
