drivers/block/zram/zram_drv.c: do not keep dangling zcomp pointer after zram reset
We do all reset operations under write lock, so we don't need to save
->disksize and ->comp to stack variables. Another thing is that ->comp is
freed during zram reset, but comp pointer is not NULL-ed, so zram keeps
the freed pointer value.
