[PATCH] ide-tape: remove redundant variable buffer_size

[Colin King]

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

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

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