tools/accounting/getdelays.c: fix netlink attribute length
commit 4054ab64e29bb05b3dfe758fff3c38a74ba753bb upstream.
A recent change to the netlink code: 6e237d099fac ("netlink: Relax attr
validation for fixed length types") logs a warning when programs send
messages with invalid attributes (e.g., wrong length for a u32). Yafang
reported this error message for tools/accounting/getdelays.c.
send_cmd() is wrongly adding 1 to the attribute length. As noted in
include/uapi/linux/netlink.h nla_len should be NLA_HDRLEN + payload
length, so drop the +1.
Fixes: 9e06d3f9f6b1 ("per task delay accounting taskstats interface: documentation fix")
