[PATCH -next] block: remove set but not used variable 'et'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

block/blk-ioc.c: In function 'put_io_context_active':
block/blk-ioc.c:174:24: warning:
 variable 'et' set but not used [-Wunused-but-set-variable]

It not used any more after commit
a1ce35fa4985 ("block: remove dead elevator code")
