USB: omap_udc: fix rejection of out transfers when DMA is used

Browse Source 
[ Upstream commit 069caf5950 ]

Commit 387f869d25 ("usb: gadget: u_ether: conditionally align
transfer size") started aligning transfer size only if requested,
breaking omap_udc DMA mode. Set quirk_ep_out_aligned_size to restore
the old behaviour.
