[PATCH 1/3] tfi: The tfi_alloc doesn't allocate anything, rename the function

[Holger Hans Peter Freyther]

From: Holger Hans Peter Freyther <holger at moiji-mobile.com>

Call things by what they do and this function doesn't allocate
anything but it is searching for the first unallocated tbf index.
