Protect against segfault if device is closed or ftdi context is invalid

This will help mulithreaded applications which do proper
locking around the ftdi_xxx() functions and one thread
already closed the USB device -> Zonk!

Ported to libftdi-1.0 with additional checks.

Thanks to Thomas Klose for reporting the issue.
