Revert "SUNRPC dont update timeout value on connection reset"

commit a275ab62 upstream.

This reverts commit 88428cc4.

The problem this commit is intended to fix was comprehensively fixed
in commit 7de62bc0 ("SUNRPC dont update timeout value on connection
reset").
Since then, this commit has been preventing the correct timeout of soft
mounted requests.
