No, this isn't just a typo fix, it's an interface change.  It's not
immediately obvious whether it's okay.

-boot parameter 'strict' appeared in commit c8a6ae8.  It was declared
QEMU_OPT_STRING, but the code using the value rejected anything but 'on'
and 'off'.  This shipped in 1.5.0.

Commit 6ef4716 accidentally dropped the code using the value of
'strict'.  Since then, any parameter value is accepted and silently
ignored.  Shipped in 1.6.0.

Your change restores the "reject anything but 'on' and 'off'" part (the
"use the value" part gets restored in the next patch).  Okay, because
the values erroneously accepted in the meantime didn't do anything.
