ia64: kprobes: Fix to pass correct trampoline address to the handler
The following commit:
Commit e792ff804f49 ("ia64: kprobes: Use generic kretprobe trampoline handler")
Passed the wrong trampoline address to __kretprobe_trampoline_handler(): it
passes the descriptor address instead of function entry address.
Pass the right parameter.
Also use correct symbol dereference function to get the function address
from 'kretprobe_trampoline' - an IA64 special.
