Alexander Kabaev 1ade5ec79a Do not pass whole descriptor block size as align to fwdma_malloc_multiseg
Do not pass wrong alignment value to fwdma_malloc_multiseg and ultimately
to contigalloc. In addition to being wrong, this causes insta-panic in
certain cases due to safety assertion - the alignment is required to be
the power of two and the value we calculate here seldom is.
