RDMA/cxgb3: Fix page shift calculation in build_phys_page_list()

Browse source

The existing logic incorrectly maps this buffer list:

    0: addr 0x10001000, size 0x1000
    1: addr 0x10002000, size 0x1000

To this bogus page list:

    0: 0x10000000
    1: 0x10002000

The shift calculation must also take into account the address of the
first entry masked by the page_mask as well as the last address+size
rounded up to the next page size.
