Revert "modpost: skip ELF local symbols during section mismatch check"
This reverts commit a4d26f1a0958bb1c2b60c6f1e67c6f5d43e2647b.
The variable 'fromsym' never starts with ".L" since commit 87e5b1e8f257
("module: Sync code of is_arm_mapping_symbol()").
In other words, Pattern 6 is now dead code.
Previously, the .LANCHOR1 hid the symbols listed in Pattern 2.
87e5b1e8f257 provided a better solution.
