bpf: Drop always true do_idr_lock parameter to bpf_map_free_id

Browse source

The do_idr_lock parameter to bpf_map_free_id was introduced by commit
bd5f5f4ecb ("bpf: Add BPF_MAP_GET_FD_BY_ID"). However, all callers set
do_idr_lock = true since commit 1e0bd5a091 ("bpf: Switch bpf_map ref
counter to atomic64_t so bpf_map_inc() never fails").

While at it also inline __bpf_map_put into its only caller bpf_map_put
now that do_idr_lock can be dropped from its signature.
