[PATCH 10/10] uml: mmapper - remove just added but wrong "const" attribute

[Paolo 'Blaisorblade' Giarrusso]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@xxxxxxxx>

When enabling the mmapper driver I got warnings because this "const" miscdevice
structure is passed to function as non-const pointer; unlike struct
tty_operations, however, I verified that misc_{de,}register _do_ modify their
parameter, so this const attribute must be removed.

Since the purpose of the change was to guarantee that no lock was needed, add a
comment to prove this differently.
