[PATCH 5.11 040/775] staging: vchiq: Fix bulk transfers on 64-bit builds

[Greg Kroah-Hartman]

From: Phil Elwell <phil@xxxxxxxxxxxxxxx>

[ Upstream commit 88753cc19f087abe0d39644b844e67a59cfb5a3d ]

The recent change to the bulk transfer compat function missed the fact
the relevant ioctl command is VCHIQ_IOC_QUEUE_BULK_TRANSMIT32, not
VCHIQ_IOC_QUEUE_BULK_TRANSMIT, as any attempt to send a bulk block
to the VPU would have shown.
