Steve French 491eafce1a smb3: fix unusable share after force unmount failure ... If user does forced unmount ("umount -f") while files are still open on the share (as was seen in a Kubernetes example running on SMB3.1.1 mount) then we were marking the share as "TID_EXITING" in umount_begin() which caused all subsequent operations (except write) to fail ... but unfortunately when umount_begin() is called we do not know yet that there are open files or active references on the share that would prevent unmount from succeeding. Kubernetes had example when they were doing umount -f when files were open which caused the share to become unusable until the files were closed (and the umount retried). Fix this so that TID_EXITING is not set until we are about to send the tree disconnect (not at the beginning of forced umounts in umount_begin) so that if "umount -f" fails (due to open files or references) the mount is still usable.
