arm64: kexec_file: return successfully even if kaslr-seed doesn't exist
In kexec_file_load, kaslr-seed property of the current dtb will be deleted
any way before setting a new value if possible. It doesn't matter whether
it exists in the current dtb.
So "ret" should be reset to 0 here.
Fixes: commit 884143f60c89 ("arm64: kexec_file: add kaslr support")
