V4L/DVB (10288): af9015: bug fix: stick does not work always when plugged
First control messages to the stick timeouts very often due to probable hw bug. Repeat first message few times if it fails as workaround. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
