smb: smbdirect: introduce smbdirect_connect[_sync]()

Browse source

This implements a fully async connect logic over
all rdma related operations: rdma_resolve_addr,
rdma_resolve_route and rdma_connect_locked
until we reach RDMA_CM_EVENT_ESTABLISHED,
followed by the smbdirect negotiation request/response
handling until we reach SMBDIRECT_SOCKET_CONNECTED.

smbdirect_connect_sync() is just a useful wrapper
around the async logic calling smbdirect_connect()
followed by smbdirect_connection_wait_for_connected(),
which only waits for SMBDIRECT_SOCKET_CONNECTED or
an error.
