tracing: fprobe: Remove __packed from generic __fprobe_header

Browse Source 
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.

[Masami: Removed Fixes tag because this is not fixing any problem.]
