[PATCH] cleanup: Fix documentation build error for ACQUIRE updates

[Dan Williams <dan.j.williams@intel.com>]

Stephen reports:

Documentation/core-api/cleanup:7: include/linux/cleanup.h:73: ERROR: Unexpected indentation. [docutils]
Documentation/core-api/cleanup:7: include/linux/cleanup.h:74: WARNING: Block quote ends without a blank line; unexpected unindent. [docutils]

Which points out that the ACQUIRE() example in cleanup.h missed the "::"
suffix to mark the following text as a code-block.

Fixes: 857d18f23ab1 ("cleanup: Introduce ACQUIRE() and ACQUIRE_ERR() for conditional locks")
