[PATCH tip/core/rcu 3/4] docs: RCU: Requirements.rst: Fix a list block

[paulmck]

From: Mauro Carvalho Chehab <mchehab+huawei@xxxxxxxxxx>

As warned by Sphinx:
	.../Documentation/RCU/Design/Requirements/Requirements.rst:1959: WARNING: Unexpected indentation.

The list block is missing a space before it, making Sphinx to get
it wrong.  This commit therefore adds the missing space characters.

Fixes: 2a721e5f0b2c ("docs: Update RCU's hotplug requirements with a bit about design")

 An offline CPU's quiescent state will be reported either:

 1.  As the CPU goes offline using RCU's hotplug notifier (``rcu_report_dead()``).
 2.  When grace period initialization (``rcu_gp_init()``) detects a
