LU-6142 lustre: remove non-static 'inline' markings.

LU-6142 lustre: remove non-static 'inline' markings.

There is rarely any point in marking a non-static function as
'inline'.  The result is to compile a state-alone function that other
files can refer to, and also to inline the code where it is used in
the same file.

In many cases the non-static inline functions are not used in the same
file, so the 'inline' marking has no effect.  In other cases it may
have an effect, but it can only be needed in highly performance
critical situations where a function call must be avoided, and that
doesn't seem like in any of these cases.

So just remove the "inline".
