The wait parameter of call_usermodehelper() is not quite a parameter
that describes the wait behaviour alone and will later be used to
request exec within a namespace.

Common kernel coding practice is to include the newline of log
prints within the log text rather than hidden away in a macro.
To avoid introducing inconsistencies as changes are made change
the log macros to not include the newline.
