io: Clear transfer timeout struct when transfer has no timeout

Browse Source 
Prior to this commit, a transfer that was submitted with a non-zero
timeout would retain this timeout if the transfer was resubmitted with
a zero (unlimited) timeout. This commit corrects this by clearing the
transfer's timeout if the desired timeout is zero.

Closes #332
