Fix all (24) kernel-doc warnings in <uapi/linux/fuse.h>:
- modify some instances to use common C comment style instead of
  kernel-doc
- convert a few instances to use kernel-doc format

The warnings are all of this form (list is truncated for brevity):

Warning: include/uapi/linux/fuse.h:370 This comment starts with '/**', but isn't a kernel-doc comment.
 * Bitmasks for fuse_setattr_in.valid
Warning: include/uapi/linux/fuse.h:386 This comment starts with '/**', but isn't a kernel-doc comment.
 * Flags returned by the OPEN request
Warning: include/uapi/linux/fuse.h:414 This comment starts with '/**', but isn't a kernel-doc comment.
 * INIT request/reply flags
Warning: include/uapi/linux/fuse.h:526 This comment starts with '/**', but isn't a kernel-doc comment.
 * CUSE INIT request/reply flags
Warning: include/uapi/linux/fuse.h:630 This comment starts with '/**', but isn't a kernel-doc comment.
 * extension type
Warning: include/uapi/linux/fuse.h:1307 This comment starts with '/**', but isn't a kernel-doc comment.
 * Header for all fuse-io-uring requests
Warning: include/uapi/linux/fuse.h:1320 This comment starts with '/**', but isn't a kernel-doc comment.
 * sqe commands to the kernel
