[Intel-gfx] [PATCH i-g-t] kms_atomic_transition: Initialize pipe_crcs to avoid segfault

[Brian Starkey]

igt_pipe_crc_new() is skipped for non-Intel devices, but the later calls
to collect_crcs_mask() will attempt to retrieve CRC values if the
pipe_crcs pointers are non-NULL.

Zero-initialise pipe_crcs to avoid accessing garbage pointers on
non-Intel devices.
