Subject: [PATCH][next] mtd: rawnand: remove redundant assignment to variable bbtblocks

The variable bbtblocks is being assigned a value that is never
read. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
drivers/mtd/nand/raw/nand_bbt.c:579:3: warning: Value stored to
'bbtblocks' is never read [deadcode.DeadStores]
