[PATCH] bcache: fix kernel-doc warning on CLOSURE_CALLBACK

[Rosen Penev <rosenp@gmail.com>]

bch_data_insert() is defined through the CLOSURE_CALLBACK() macro, which
kernel-doc cannot see through, so the kernel-doc comment above it
produces:

  request.c:308 function parameter 'bch_data_insert' not described in 'CLOSURE_CALLBACK'
  request.c:308 expecting prototype for bch_data_insert(). Prototype was for CLOSURE_CALLBACK() instead

Turn it into a regular block comment, and drop the @cl line along
with the kernel-doc markup.
