[patch 071/114] drivers/rapidio/devices/tsi721_dma.c: delete an unnecessary variable initialisation in tsi721_alloc_chan_resources()

[akpm]

From: Markus Elfring <elfring@users.sourceforge.net>
Subject: drivers/rapidio/devices/tsi721_dma.c: delete an unnecessary variable initialisation in tsi721_alloc_chan_resources()

The local variable "desc" will eventually be set to an appropriate pointer
a bit later. Thus omit the explicit initialisation at the beginning.
