Fix inline send posting when posting more than one request
Need to set inl parameter to zero for each request when posting a list
of requests, so that the value of inl is correct for each work
request, and is not cumulative.

Implement posting of RDMA and atomic operations
Clean up the definitions of remote address and atomic operations WQE
segments. Fill in the missing code that fills in these segments when
posting RDMA or atomic operations to a send queue.

Multiple SRQ fixes
Several one-liner fixes to SRQ support:
- Scatter entry address is 64 bits, so use htonll() instead of
htonl() when filling in WQE.
- Minimum SRQ WQE size is 32 bytes, so use 5 as a minimum value of
wqe_shift.
- When initializing next_wqe_index values, use htons() to put indices
into big-endian byte order.

Don't set last byte of GID for non-global address vectors
Previous generation HCAs needed the last byte of the GID set to 2 for
non-global address vectors, but ConnectX just ignores the remote GID
field for non-global AVs, so remove the unnecessary code that sets it.

Implement handling for completions with error
Convert status from HCA's hardware values to libibverbs enum for
completions with error in mlx4_handle_error_cqe(). Also, there's no
way mlx4_handle_error_cqe() can fail, so there's no reason for it to
return a value.

Simplify completion with error handling
The out-of-line function to handle error CQEs doesn't need as many
parameters as the libmthca version did, so get rid of everything
except the CQE pointer and the WC pointer.
