feat: add iscsi_reset_next_reconnect interface

Browse Source 
When an iSCSI connection enters the reconnection phase, the backoff
time (next_reconnect) increases with reconnection retry_cnt. However,
if the client detects that the target has recovered before reaching
next_reconnect, calling iscsi_reconnect/iscsi_force_reconnect has no
any effect, making fast reconnection impossible.

This patch introduces an interface to reset next_reconnect, so that
the client can reset the backoff time upon detecting target recovery
and achieve faster reconnection.
