Clang warns:

../drivers/staging/media/atomisp/pci/sh_css.c:8545:14: warning: address
of 'pipe->vf_stage' will always evaluate to 'true'
[-Wpointer-bool-conversion]
                if (&pipe->vf_stage)
                ~~   ~~~~~~^~~~~~~~

output_stage and vf_stage are pointers in the middle of a struct, their
addresses cannot be NULL if pipe is not NULL and pipe is already checked
for NULL in this function. Simplify this if block.
