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