Jiayuan Chen 452a927cdd bpf: Drop task_to_inode and inet_conn_established from lsm sleepable hooks ...

[ Upstream commit beaf0e96b1 ]

bpf_lsm_task_to_inode() is called under rcu_read_lock() and
bpf_lsm_inet_conn_established() is called from softirq context, so
neither hook can be used by sleepable LSM programs.

Fixes: 423f16108c ("bpf: Augment the set of sleepable LSM hooks")
