iwlegacy: remove several redundant variables
Variables id, unicast, write, conf, a_band, accum_tx and ucode are
assigned a value but it is never read, hence they are redundant and
can be removed.
Cleans up clang warnings:
warning: variable 'id' set but not used [-Wunused-but-set-variable]
warning: variable 'unicast' set but not used [-Wunused-but-set-variable]
warning: variable 'write' set but not used [-Wunused-but-set-variable]
warning: variable 'conf' set but not used [-Wunused-but-set-variable]
warning: variable 'a_band' set but not used [-Wunused-but-set-variable]
warning: variable 'tx' set but not used [-Wunused-but-set-variable]
warning: variable 'accum_tx' set but not used [-Wunused-but-set-variable]
warning: variable 'ucode' set but not used [-Wunused-but-set-variable]
