ASoC: Intel: FW Loader: Skip allocation for other than IRAM/DRAM blocks

Since we are managing only fixed IRAM and DRAM blocks by registering them
using sst_mem_block_register() during basic initialization we don't find
blocks for extended firmware when calling module_alloc_fixed_block() from
sst_module_insert_fixed_block(). This caused that extended firmware parts
from firmware file were not uploaded.

Fix this by skipping allocation for other than IRAM/DRAM in
module_alloc_fixed_block().
