doc: update mount.cifs man page with nounix option
Change since last post:
- fix build error due to superfluous </para> tag.
- ensure it builds fine.
Also add a section on INODE NUMBERS that discusses inode numbers more
thoroughly and add reference to it in "nounix" and "noserverino"
options.
Thanks to Jeff Layton for explaining those details.

+ Note that the UniqueID is a different value from the server

+ structure field. It is strongly recommended to compile your programs
+ with LFS support (i.e. with -D_FILE_OFFSET_BITS=64) to prevent this
+ problem. You can also use "noserverino" mount option to generate inode
+ numbers smaller than 2 power 32 on the client. But you may not be able
