bpf: fix possible file descriptor leaks in verifier
The resolve_pseudo_ldimm64() function might have leaked file
descriptors when BPF_MAP_TYPE_ARENA was used in a program (some
error paths missed a corresponding fdput). Add missing fdputs.
v2:
remove unrelated changes from the fix
Fixes: 6082b6c328b5 ("bpf: Recognize addr_space_cast instruction in the verifier.")
