Since commit 3ef0e5ba4673 ('slab: introduce kzfree()'),
kfree() is no more the only function to be considered:
kzfree() should be recognized too.
In particular, kzfree() must not be called on memory
allocated through devm_*() functions.

This patch ensures that all semantic patches in the scripts/coccinelle
directory provide the report option. Report messages that include line
numbers now have the line number preceded by "line" for easier subsequent
processing.

Find a use after free. Values of variables may imply that some
execution paths are not possible, resulting in false positives.
Another source of false positives are macros such as
SCTP_DBG_OBJCNT_DEC that do not actually evaluate their argument
