[PATCH] staging: speakup: remove redundant variable l

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

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

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