Coly Li fc2d5988b5 bcache: add identifier names to arguments of function definitions
There are many function definitions do not have identifier argument names,
scripts/checkpatch.pl complains warnings like this,

 WARNING: function definition argument 'struct bcache_device *' should
  also have an identifier name
  : FILE: writeback.h:120:
  +void bch_sectors_dirty_init(struct bcache_device *);

This patch adds identifier argument names to all bcache function
definitions to fix such warnings.
