Bug Description

The test sys_vars.innodb_buffer_pool_load_now_basic is unstable even after bug 1625187 fix:

sys_vars.innodb_buffer_pool_load_now_basic w4 [ fail ]
        Test ended at 2016-12-29 08:13:49

CURRENT_TEST: sys_vars.innodb_buffer_pool_load_now_basic
mysqltest: At line 24: command "file_exists" failed with error 1. my_errno=175

The result from queries just before the failure was:
SET @orig = @@global.innodb_buffer_pool_load_now;
SELECT @orig;
SET GLOBAL innodb_buffer_pool_dump_now = ON;
safe_process[29944]: Child process: 29945, exit: 1
