Check for errno == EBADF in kmtIoctl to detect misuse of the kfd_fd
in a forked child process.
Detect being in a forked child process pro-actively by implementing
a pthread_atfork callback.
Make sure all mutexes get reinitialized in the child process to avoid
deadlocks.
Check for being in a forked child process in CHECK_KFD_OPENED so that
all hsaKmt functions will return the appropriate status
HSAKMT_STATUS_KERNEL_IO_CHANNEL_NOT_OPENED.
Update InvalidKFDHandleTest to expect that error code.
