RDMA/mana_ib: advertise pow2 RC SQ support to user space

The send queue of an RC QP normally needs an extra rollback area in
shared memory. With fixed-size WQEs the rollback can be derived from the
WQE size alone, so an adapter supporting it can accept a plain
power-of-two send queue and the rollback area becomes unnecessary.

Report the adapter capability to user space with a new comp_mask bit in
the alloc ucontext response, so that user space can request a
power-of-two RC send queue when the adapter supports it.
