From: Geliang Tang <tanggeliang@kylinos.cn>

Double the data size in nonblocking tests to accommodate MPTCP's
multi-subflow behavior and ensure sufficient data for testing,
avoiding the following errors:

 #  RUN           tls.12_aria_gcm_mptcp.nonblocking ...
 # tls.c:1534:nonblocking:Expected 0 (0) != eagain (0)
 # nonblocking: Test failed
