[PATCH] staging: greybus: remove redundant assignment to variable is_empty

[Colin King]

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

The variable is_empty is being initialized with a value that is never
read and it is being updated later with a new value. The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
