[PATCH net v2 5/5] net/netlink: Correct the comment on netlink message max cap

[Dmitry Safonov via B4 Relay <devnull+0x7f454c46.gmail.com@kernel.org>]

From: Dmitry Safonov <0x7f454c46@gmail.com>

Since commit d35c99ff77ec ("netlink: do not enter direct reclaim from
netlink_dump()") the cap is 32KiB.
