[PATCH 2/3] common/rc: Add _require_get_hugepagesize and fix _require_label_get_max

[Ritesh Harjani <riteshh@linux.ibm.com>]

_notrun executed from a subshell $(cmd) won't exit it's parent.
Hence _require_*** functions shouldn't have below statements.
	dummy=$(_label_get_max)
Also add a function _require_get_hugepagesize(), since it seems the
intention of _get_hugepagesize() is to also '_notrun' when the hugepagesize
is not a valid number.
