USB: EHCI: fix DMA deallocation bug
commit f75593ceaa08e6d27aec1a5de31cded19e850dd1 upstream.
This patch (as1440) fixes a bug in ehci-hcd. ehci->periodic_size is
used to compute the size in a dma_alloc_coherent() call, but then it
gets changed later on. As a result, the corresponding call to
dma_free_coherent() passes a different size from the original
allocation. Fix the problem by adjusting ehci->periodic_size before
carrying out any of the memory allocations.
