Subject[PATCH] bcache: remove set but not used variable 'i'
Date
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/md/bcache/btree.c: In function bch_btree_check_thread:
drivers/md/bcache/btree.c:1910:6: warning:
variable ‘i’ set but not used [-Wunused-but-set-variable]

It's not used since commit 8e7102273f59 ("bcache: make bch_btree_check()
to be multithreaded"), so remove it.
