staging: zsmalloc: fix uninit'ed variable warning
This patch fixes an uninitialized variable warning in
alloc_zspage(). It also fixes the secondary issue of
prev_page leaving scope on each loop iteration. The only
reason this ever worked was because prev_page was occupying
the same space on the stack on each iteration.
