[PATCH] udf: remove unused variables group_start and nr_groups

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Variables group_start and nr_groups are being assigned but are never used
hence they are redundant and can be removed.

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