tools/init-xenstore-domain: Replace variable MB() usage

The local MB() & GB() macros will be replaced with a common
implementation, but those only work with numeric values. Introduce a
static inline mb_to_bytes() in place of the MB() macro to convert the
variable values, at the same time addressing the lack of
parenthesization of the prior macro's parameter.
