Fix the following kernel-doc warning in include/linux/fs.h:

  WARNING: ./include/linux/fs.h:3287 function parameter 'name' not described in 'name_contains_dotdot'

The function comment for name_contains_dotdot() did not describe its
@name argument.
Updated the function comment by adding @name parameter description.

Fixes: 0da3e3822cfa ("fs: move name_contains_dotdot() to header")
