arm64: uaccess: Remove redundant __force from addr cast in __range_ok

Browse Source 
Casting a pointer to an integral type doesn't require a __force
attribute, because you'll need to cast back to a pointer in order to
dereference the thing anyway.

This patch removes the redundant __force cast from __range_ok.
