OvmfPkg/XenBusDxe: In XenStore, replace type of Len from UINTN to UINT32.

Browse Source 
Since a message to XenStore have a lenght of type UINT32, have
XenStore.c deal only with UINT32 instead of a mixmatch with UINTN.

This patch replaces the type of Len in WRITE_REQUEST and the type of the
argument Len of XenStoreWriteStore and XenStoreReadStore.

This patch should avoid to have type cast were it does not make sense to
have them.
