This patch fixes and preserves existing code style, and readability,
for IWL_ERR() and IWL_WARN() macros invocations recently added in dbg.c

Fixes the following build errors with Android build system:

/home/utente/pie-x86_kernel/kernel/drivers/net/wireless/intel/iwlwifi/fw/dbg.c: In function '_iwl_fw_dbg_apply_point':
/home/utente/pie-x86_kernel/kernel/drivers/net/wireless/intel/iwlwifi/fw/dbg.c:2445:3:
error: call to '__compiletime_assert_2446' declared with attribute error: BUILD_BUG_ON failed: err_str[sizeof(err_str) - 2] != '\n'
/home/utente/pie-x86_kernel/kernel/drivers/net/wireless/intel/iwlwifi/fw/dbg.c:2451:3:

error: call to '__compiletime_assert_2801' declared with attribute error: BUILD_BUG_ON failed: invalid_ap_str[sizeof(invalid_ap_str) - 2] != '\n'

Fixes: 57d88b116175 ("iwlwifi: dbg_ini: support debug info TLV")
