fix semantic error: no entrypc found using probe .statement(*@file:line) constructs
At the moment, you can't specify
probe module("scsi_mod").statement(*@drivers/scsi/scsi_lib.c:1443)
because the compiler will fail with the above semantic error on the
function scsi_end_bidi_request. It seems looking through the dwarf that
this function is fully inlined and thus has no entrypc to catalogue.
The solution therefore seems to simply return DWARF_CB_OK when we find
such functions and continue cataloguing all the ones that do actually
have non-inline versions.
