aarch64: properly initialize def_protected member

Hi.

"aarch64: Disallow copy relocations on protected data" [1] commit unfortunately
does not initialize def_protected member.

This leads to spurious "copy relocation against non-copyable protected symbol"
errors as def_protected member might not be touched (if definition is false)
and the allocation routine (bfd_hash_allocate/objalloc_alloc) does not appear
to zero initialize allocated space.

Attached a patch proposal.
