[PATCH] pstore: remove redundant initialization of variable zipped_len

[Colin King]

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

The variable zipped_len 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. Clean up the code
and move the scope of zipped_len.

Addresses-Coverity: ("Unused value")
