Subject: [PATCH] media: vim2m: Fix abort issue

Currently, if start streaming -> stop streaming -> start streaming
sequence is executed, driver will end job prematurely, if ctx->translen
is higher than 1, because "aborting" flag is still set from previous
stop streaming command.

Fix that by clearing "aborting" flag in start streaming handler.

Hi!

This was only compile tested. Any suggestion how to properly test it
would be appreciated.

Best regards,
Jernej
