usb: ci_udc: don't memalign() struct ci_req allocations
struct ci_req is a purely software structure, and needs no specific memory alignment. Hence, allocate it with calloc() rather than memalign(). The use of memalign() was left-over from when struct ci_req was going to hold the aligned bounce buffer, but this is now dynamically allocated. Signed-off-by: Stephen Warren <swarren@nvidia.com>
