Detailed Description

Represents a wrapper over generic IO fop and its callback to keep track of such IO fops issued by the same target_ioreq structure.

When bottom halves for m0_sm_ast structures are run, it updates target_ioreq::ti_rc and target_ioreq::ti_bytes with data from IO reply fop. Then it decrements nw_xfer_request::nxr_iofop_nr, number of IO fops. When this count reaches zero, io_request::ir_sm changes its state.
