drm/i915/fb: Use intel_fb_needs_pot_stride_remap() in intel_fb_view_init()

Replace the open coded intel_fb_needs_pot_stride_remap() check
inside intel_fb_view_init() with the real thing.

The current check doesn't have the intel_fb_uses_dpt() in there, but
that is the only situation when we use the remapped view, and thus
was always implied.
