libiscsi: return new error code when nop times out
When a iscsi nop as ping timedout we were failing with the common connection error code, ISCSI_ERR_CONN_FAILED. This patch adds a new error code for this problem so can properly track/distinguish in userspace. Signed-off-by:Mike Christie <michaelc@cs.wisc.edu> Acked-by:
