perf bpf: Fix map data leak in bpf_metadata_create() on alloc failure

bpf_metadata_create() calls bpf_metadata_read_map_data() which
allocates map.btf and map.rodata.  If the subsequent
bpf_metadata_alloc() fails, the code does 'continue' which skips
bpf_metadata_free_map_data(), permanently leaking both allocations.

Fix by calling bpf_metadata_free_map_data() before continue.
