tcf_act_police_init() can fail after the idr has been successfully
reserved (e.g., qdisc_get_rtab() may return NULL). When this happens,
subsequent attempts to configure a police rule using the same idr value
systematiclly fail with -ENOSPC:
# tc action add action police rate 1000 burst 1000 drop index 100
RTNETLINK answers: Cannot allocate memory

Fix this in the error path of tcf_act_police_init(), calling
tcf_idr_release() in place of tcf_idr_cleanup().

if the kernel fails to duplicate 'sdata', creation of a new action fails

that value of 'index' will no more be usable by act_simple, until rmmod /

act_bpf correctly refuses to install the first TC rule, because 31 is not
a valid instruction. However, it refuses to install the second TC rule,
even if the BPF code is correct. Furthermore, it's no more possible to
install any other rule having the same value of 'index' until act_bpf
module is unloaded/inserted again. After the idr has been reserved, call
tcf_idr_release() instead of tcf_idr_cleanup(), to fix this issue.

Under some heavy computing environment(e.g. dgemm test), it
takes the asic over 10+ seconds to finish the dispatched job
