mtd: rawnand: diskonchip: Marking unused variables as __always_unused
'dummy' is never checked (as per the nomenclature) and the use of
'emtpymatch' is currently #if 0'ed out. We could also #if 0 the
declaration, but #ifery is pretty ugly, so I like to keep it to a
minimum.
Fixes the following W=1 kernel build warning(s):
drivers/mtd/nand/raw/diskonchip.c: In function ‘DoC_Delay’:
drivers/mtd/nand/raw/diskonchip.c:219:16: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable]
drivers/mtd/nand/raw/diskonchip.c: In function ‘doc200x_calculate_ecc’:
drivers/mtd/nand/raw/diskonchip.c:706:6: warning: variable ‘emptymatch’ set but not used [-Wunused-but-set-variable]
