libhsakmt: Improve error handling in child process

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.

Clean up thunk code

Use checkpatch.pl to fix the majority of errors. Some that remain and
will be excluded:
Use of typedefs/externs/volatile/sscanf
Lines over 80 characters

Remaining errors are due to misunderstanding the * symbol with typedefs

Also use this opportunity to spell manageable properly
