[PATCH 5.16 0643/1017] staging: r8188eu: release_firmware is not called if allocation fails

[ Upstream commit 39850edf2befe27bcb3d6c37b6ee76d2ee4df903 ]

In function load_firmware() release_firmware() is not called if the
allocation of pFirmware->szFwBuffer fails or if fw->size is greater
than FW_8188E_SIZE.

Move the call to release_firmware() to the exit label at the end of
the function to fix this.
