firmware: raspberrypi: fix possible memory leak in rpi_firmware_probe()
[ Upstream commit 7b51161696e803fd5f9ad55b20a64c2df313f95c ]
In rpi_firmware_probe(), if mbox_request_channel() fails, the 'fw' will
not be freed through rpi_firmware_delete(), fix this leak by calling
kfree() in the error path.
