IB/core: Change idr objects to use the new schema
This changes only the handlers which deals with idr based objects to use the new idr allocation, fetching and destruction schema. This patch consists of the following changes: (1) Allocation, fetching and destruction is done via idr ops. (2) Context initializing and release is done through uverbs_initialize_ucontext and uverbs_cleanup_ucontext. (3) Ditching the live flag. Mostly, this is pretty straight forward. The only place that is a bit trickier is in ib_uverbs_open_qp. Commit [1] added code to check whether the uobject is already live and initialized. This mostly happens because of a race between open_qp and events. We delayed assigning the uobject's pointer in order to eliminate this race without using the live variable.
