Convert page cache read to VOP.
There are several negative side-effects of not calling into VOP layer at all for page cache reads. The biggest is the missed activation of EVFILT_READ knotes. Also, it allows filesystem to make more fine grained decision to refuse read from page cache. Keep VIRF_PGREAD flag around, it is still useful for nullfs, and for asserts.
