[PATCH] usb: ati remote memleak fix

[Mariusz Kozlowski <m.kozlowski@tuxland.pl>]

Hello,

	This is a bug. When checking for ati_remote->outbuf we free
freeing ati_remote->inbuf so we end up freeing ati_remote->inbuf twice.
Also the checks for 'ati_remote->inbuf != NULL' and
'ati_remote->outbuf != NULL' are redundant as usb_buffer_free() does
this.
