syzbot reported a general protection fault caused by a null pointer
dereference in coalesce_fill_reply(). The issue occurs when req_base->dev
is null, leading to an invalid memory access.
This panic occurs if dumping coalesce when no device name is specified.
Fixes: f750dfe825 ("ethtool: provide customized dim profile management")
