fp pointer and unsigned long have the same size on all relevant
architectures that build Linux. Furthermore this struct is only used in
architectures that do not set ARCH_DEFINE_ENCODE_FPROBE_HEADER which is
set only for 64bit architectures (apart from LoongArch).
Both fields are aligned on these architectures so the struct with
__packed and without it are the same.
Remove the __packed as it is unnecessary.
