wifi: iwlwifi: dbg_ini: fix structure packing

[ Upstream commit 424c82e8 ]

The iwl_fw_ini_error_dump_range structure has conflicting alignment
requirements for the inner union and the outer struct:

In file included from drivers/net/wireless/intel/iwlwifi/fw/dbg.c:9:
drivers/net/wireless/intel/iwlwifi/fw/error-dump.h:312:2: error: field  within 'struct iwl_fw_ini_error_dump_range' is less aligned than 'union iwl_fw_ini_error_dump_range::(anonymous at drivers/net/wireless/intel/iwlwifi/fw/error-dump.h:312:2)' and is usually due to 'struct iwl_fw_ini_error_dump_range' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]
        union {

As the original intention was apparently to make the entire structure
unaligned, mark the innermost members the same way so the union
becomes packed as well.
