module: Remove unnecessary +1 from last_unloaded_module::name size

The variable last_unloaded_module::name tracks the name of the last
unloaded module. It is a string copy of module::name, which is
MODULE_NAME_LEN bytes in size and includes the NUL terminator. Therefore,
the size of last_unloaded_module::name can also be just MODULE_NAME_LEN,
without the need for an extra byte.

Fixes: e14af7eeb47e ("debug: track and print last unloaded module in the oops trace")
