Christophe JAILLET c7eaf15c2c dmaengine: pxa_dma: Remove an erroneous BUG_ON() in pxad_free_desc() 
[ Upstream commit 83c761f568733277ce1f7eb9dc9e890649c29a8c ]

If pxad_alloc_desc() fails on the first dma_pool_alloc() call, then
sw_desc->nb_desc is zero.
In such a case pxad_free_desc() is called and it will BUG_ON().

Remove this erroneous BUG_ON().

It is also useless, because if "sw_desc->nb_desc == 0", then, on the first
iteration of the for loop, i is -1 and the loop will not be executed.
(both i and sw_desc->nb_desc are 'int')

Fixes: a57e16cf0333 ("dmaengine: pxa: add pxa dmaengine driver")
