[PATCH] ARM64:ftrace: fix ftrace_modify_graph_caller for branch replace

[Pratyush Anand]

ftrace_enable_ftrace_graph_caller and ftrace_disable_ftrace_graph_caller
should replace B(jmp) instruction and not BL(call) instruction.

patch 9f1ae7596aad71d18c3e88a3927f3f76b037b8fe did a typo and used
AARCH64_INSN_BRANCH_LINK instead of AARCH64_INSN_BRANCH_NOLINK.
