Previously, workbuf used was not rounded up to a multiple of VB2_WORKBUF_ALIGN. The next allocation would be aligned, but not until it was made. Change this to round up used size when more workbuf is used. This provides better predictability of where the next allocation will be placed. Uncovered this problem when I added a new member to vb2_shared_data which changed its size so it wasn't a multiple of VB2_WORKBUF_ALIGN, and the vb20 and vb21 unit tests which tried to simulate not enough buffer broke in strange ways.
