[bladeRF-cli] First open fails when device has incompatible FPGA/FW

[jynik]

When the bladeRF has an incompatible firmware or FPGA image, the first open with the bladeRF-cli (i.e., the open that triggers the FPGA autoload) will not allow the user to continue in the CLI to perform the upgrade.

$  bladeRF-cli -i                                                                                                                                                                                                                         
[WARNING @ fpga.c:53] FPGA v0.5.0 was detected. Firmware v2.1.0 requires FPGA v0.6.0 or later. Please load a different FPGA version before continuing.

$  bladeRF-cli -i

Workaround: Run the CLI twice 😢
