staging: zsmalloc: s/firstpage/page in new copy map funcs
firstpage already has precedent and meaning the first page of a zspage. In the case of the copy mapping functions, it is the first of a pair of pages needing to be mapped. This patch just renames the firstpage argument to "page" to avoid confusion.
