[PATCH] drm/imagination: vm: Fix heap lookup condition

[Alex Bee <knaerzche@gmail.com>]

When conditionally checking for heap existence of a certian address in
pvr_vm_bind_op_map_init the condition whether the map request comes from a
user is incorrect: The context must not be the kernel-context to be a
user(space) context and should be looked up in pvr_heaps.

That makes addresses coming from userspace not being verfied against the
defined ranges and prevents firmware loading for meta cores.

Fixes: ff5f643de0bf ("drm/imagination: Add GEM and VM related code")
