[v6,22/33] target: Inline transport_check_aborted_status()

Commit Message

Bart Van Assche Feb. 15, 2017, 12:26 a.m. UTC

Due to the previous patch the second argument of
transport_check_aborted_status() is ignored and that function does
no longer have any side effect. Hence remove all calls of that
function that do not check the return value. Additionally, inline
this function.
