i386: Don't insert ENDBR after NOTE_INSN_DELETED_LABEL
NOTE_INSN_DELETED_LABEL is used to mark what used to be a 'code_label',
but was not used for other purposes than taking its address which cannot
be used as target for indirect jumps.
Tested on Linux/x86-64 with -fcf-protection.
For x86-64 libc.so on glibc master branch (commit f43b8dd55588c3),
Before: 2961 endbr64
After: 2943 endbr64
