mm/zram: correct ZRAM_ZERO flag bit position
In struct zram_table_entry, the element *value* contains obj size and obj
zram flags. Bit 0 to bit (ZRAM_FLAG_SHIFT - 1) represent obj size, and
bit ZRAM_FLAG_SHIFT to the highest bit of unsigned long represent obj
zram_flags. So the first zram flag(ZRAM_ZERO) should be from
ZRAM_FLAG_SHIFT instead of (ZRAM_FLAG_SHIFT + 1).
This patch fixes this cosmetic issue.
Also fix a typo, "page in now accessed" -> "page is now accessed"
