wifi: iwlwifi: fw: avoid using an uninitialized variable

Browse Source 
iwl_fwrt_read_err_table can return true also when it failed to read
the memory. In this case, err_id argument is not initialized,
but the callers are still using it.

Simply initialize it to 0. If the error table was read successfully it'll
be overridden.
