[PATCH] fscache: fix misdocumented parameter name

[Khalid Masum <khalid.masum.92@gmail.com>]

To fix warning generated by make docs in the file fscache.h:
The functions fscache_use_cookie and fscache_unuse_cookie have a
parameter named cookie. But they are documented with the name "object".
Which generates warning when creating docs. This commit will replace
the documentation with a better one named "cookie". This new
documentation
line is taken from the function fscache_update_cookie in the same
file.
