class_devno_max is an inline function that is written with
the sole purpose of returning the value of MAX_OBD_DEVICES.
Since no computations are made by the class_devno_max,
replace it with MAX_OBD_DEVICES.

class_devno_max is an inline function that is not used
anymore. Hence, it is removed.

Thanks for your patch, but unfortunately it can't be accepted.
This function was added in preparation of being able to tune the maximum
number of storage devices dynamically, rather than having to hard code it
to the maximum possible number of servers that a client can possibly
connect to.
While the current maximum of 8192 servers has been enough for current
filesystems, I'd rather move in the direction of dynamically handling this
limit rather than re-introducing a hard-coded constant throughout the code.
One comment inline below, if you still want to submit a patch.

This block can just be removed entirely. It used to do something useful,
but through a series of changes it has become useless.
