Subject: [PATCH] Grow_continue_command: ensure 'content' is properly
 initialised.
Git-commit: a250ce240f245df594570a5e25398680d403af67
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

Grow_continue_command() call verify_reshape_position(), which assumes
that info->sys_name is initialised.
'info' in verify_reshape_position() is 'content' in Grow_continue_command().

In the st->ss->external != 0 branch of that function, sysfs_init() is called
to initialize content->sys_name.
In the st->ss->external == 0 branch, ->sys_name is not initialized so
verify_reshape_position() will not do the right thing.
