[Silabs][Wi-Fi]- Update to 917 soc freertos settings (project-chip#31071

)

* Unused variable status in sl_wifi_if.c

* Increased HEAP Size for SOC DIC AWS OTA

* Restyled by clang-format

* Removed typo mistake

* Removing the wfx_rsi_alloc_pkt API from sl_wifi_if.c as it is not being used anywhere in code for 917NCP and SOC boards.
