Hello build bot (Jenkins), Nico Huber, Miklós Márton, Miklós Márton, Edward O'Callaghan, Angel Pons,

I'd like you to reexamine a change. Please visit

stlinkv3_spi.c: Clean up properly on all init error paths

Do a cleanup: close handle and exit usb context in cases when init
fails.

If register_spi_master() fails, going to err_exit cleanup is not
needed because at that point shutdown function has already been
registered and it does the job.
