nubus: Kill nubus_proc_detach_device()

Commit 59d8053f1e16904d54ed7469d4b36801ea6b8f2c ("proc: Move non-public
stuff from linux/proc_fs.h to fs/proc/internal.h") broke Apple NuBus
support:

drivers/nubus/proc.c: In function ‘nubus_proc_detach_device’:
drivers/nubus/proc.c:156: error: dereferencing pointer to incomplete type
drivers/nubus/proc.c:158: error: dereferencing pointer to incomplete type

Fortunately nubus_proc_detach_device() is unused, and appears to have never
been used, so just remove it.
