ftrace: fix build failure 

After disabling FTRACE_MCOUNT_RECORD via a patch, a dormant build
failure surfaced:

 kernel/trace/ftrace.c: In function 'ftrace_record_ip':
 kernel/trace/ftrace.c:416: error: incompatible type for argument 1 of '_spin_lock_irqsave'
 kernel/trace/ftrace.c:433: error: incompatible type for argument 1 of '_spin_lock_irqsave'

Introduced by commit 6dad8e07f4c10b17b038e84d29f3ca41c2e55cd0 ("ftrace:
add necessary locking for ftrace records").
