[PATCH 3.16 081/410] rcutorture/kvm.sh: Use consistent help text for --qemu-args

[Ben Hutchings]

3.16.57-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: SeongJae Park <sj38.park@xxxxxxxxx>

commit 8dcd6f3fe206c0bb8996e59386a04027b1c2fb9b upstream.

The '--qemu-args' option's help text is wrongly copied from '--qemu-cmd'
option and its argument type description message format is inconsistent
with other arguments.  This commit fixes the usage and type messages to
be consistent with others.

Fixes: e9ce640001c6 ("rcutorture: Add --qemu-args argument to kvm.sh")
