block: misc ioc cleanups
* int return from put_io_context() wasn't used by anybody. Make it
return void like other put functions and docbook-fy the function
comment.
* Reorder dummy declarations for !CONFIG_BLOCK case a bit.
* Make alloc_ioc_context() use __GFP_ZERO allocation, take init out of
if block and drop 0'ing.
* Docbook-fy current_io_context() comment.
This patch doesn't introduce any functional change.
