pwm: Fix out-of-bounds access in of_pwm_single_xlate()

With args->args_count == 2 args->args[2] is not defined. Actually the
flags are contained in args->args[1].

According to the comment of `nla_parse_nested_deprecated`, the maxtype
should be len(destination array) - 1. Hence use `IFLA_RMNET_MAX` here.

netfilter: nf_tables: reject QUEUE/DROP verdict parameters

This reverts commit e0abdadcc6e1.

core.c:nf_hook_slow assumes that the upper 16 bits of NF_DROP
verdicts contain a valid errno, i.e. -EPERM, -EHOSTUNREACH or similar,
or 0.

Due to the reverted commit, its possible to provide a positive
value, e.g. NF_ACCEPT (1), which results in use-after-free.

Its not clear to me why this commit was made.

NF_QUEUE is not used by nftables; "queue" rules in nftables
will result in use of "nft_queue" expression.

If we later need to allow specifiying errno values from userspace
(do not know why), this has to call NF_DROP_GETERR and check that
"err <= 0" holds true.
