There is no need to additionally use f2fs_show_injection_info()
to output information. Concatenate time_to_inject() and
__time_to_inject() via a macro. In the new __time_to_inject() function,
pass in the caller function name.
In this way, we no longer need the f2fs_show_injection_info() function,
and let's remove it.

__builtin_return_address(0) result changes from return address of caller of
