arm64: ftrace: prepare ftrace_modify_call() for use without CALL_OPS

ftrace_modify_call() is guarded by CONFIG_DYNAMIC_FTRACE_WITH_CALL_OPS and
calls ftrace_rec_set_ops(rec, arm64_rec_get_ops(rec)) directly, which only
exists when CALL_OPS is enabled.

Generic ftrace also needs ftrace_modify_call() when
CONFIG_DYNAMIC_FTRACE_WITH_DIRECT_CALLS is enabled, to retarget a callsite
between two non-FTRACE_ADDR destinations, as happens when a direct
trampoline is modified. The next patch allows DIRECT_CALLS without CALL_OPS,
so widen the guard to cover both configurations and switch the body to the
ftrace_rec_update_ops() wrapper, which already has a stub for the !CALL_OPS
case. ftrace_make_call() already uses the same wrapper today.

No functional change: with CALL_OPS enabled, ftrace_rec_update_ops() expands
to the exact call this replaces.
