[PATCH] mtd: nftl: remove redundant variable nb_erases

[colin.king@xxxxxxxxxxxxx (Colin King)]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable nb_erases is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'nb_erases' set but not used [-Wunused-but-set-variable]
