Menglong Dong 0a6c0fc1f8 ftrace: fix incorrect hash size in register_ftrace_direct() ...

[ Upstream commit 92f1d3b40179b15630d72e2c6e4e25a899b67ba9 ]

The maximum of the ftrace hash bits is made fls(32) in
register_ftrace_direct(), which seems illogical. So, we fix it by making
the max hash bits FTRACE_HASH_MAX_BITS instead.
