Subject: perf annotate: Return appropriate error code for allocation failures
Git-commit: 16ed3c1e91159e28b02f11f71ff4ce4cbc6f99e4
Patch-mainline: 5.4-rc3
References: bnc#1151927 5.3.9

We should return errno or the annotation extra range understood by
symbol__strerror_disassemble() instead of -1, fix it, returning ENOMEM
instead.
