[GPFS] Fix to let GPFS upcall thread exit at ganesha startup
Currently during startup if GPFSFSAL_UP_Thread() gets called, it
waits in nfs_init_wait() for init to complete. But if during startup
gpfs_unclaim_filesystem() gets called, then the main thread may hang
at pthread_join() for GPFS upcall thread, if the thread is waiting in
nfs_init_wait().
To avoid this made use of 'stop_thread' variable in
'struct gpfs_filesystem', which is set to 'true' prior to calling
pthread_join() in gpfs_unclaim_filesystem(). Also made changes to
allow to pass timeout value to nfs_init_wait() which is now called
in GPFSFSAL_UP_Thread() in while(1) loop, and after nfs_init_wait()
completes if gpfs_fs->stop_thread==true then we return.
