[PATCH 05/62] dma-buf: Convert dma_buf_import_sync_file() to the early-return style

[Bart Van Assche <bart.vanassche@linux.dev>]

From: Bart Van Assche <bvanassche@acm.org>

Before making changes in dma_buf_import_sync_file(), convert it to
the early-return coding style. No functionality has been changed.
