Let address_space_rw() calls pass a boolean 'is_write' argument

Since its introduction in commit ac1970fbe8, address_space_rw()
takes a boolean 'is_write' argument. Fix the codebase by using
an explicit boolean type.

This commit was produced with the included Coccinelle script
scripts/coccinelle/exec_rw_const.
