Masahiro Yamada 1102f9f85b modpost: do not make find_tosym() return NULL
As mentioned in commit 397586506c ("modpost: Add '.ltext' and
'.ltext.*' to TEXT_SECTIONS"), modpost can result in a segmentation
fault due to a NULL pointer dereference in default_mismatch_handler().

find_tosym() can return the original symbol pointer instead of NULL
if a better one is not found.

This fixes the reported segmentation fault.

Fixes: a23e7584ec ("modpost: unify 'sym' and 'to' in default_mismatch_handler()")
