[OSSTEST Nested PATCH v9 5/9] Move the codes about memory size setting into prep()

["longtao.pang" <longtaox.pang@intel.com>]

From: "longtao.pang" <longtaox.pang@intel.com>

Move the codes about memory size setting from outside into prep(),
where these $ram_mb operations are only used; and in next patch,
for L2 guest installation, $ram_mb will be override by a runvar value,
which needs $gho in scope.
