media: dvb: return -EREMOTEIO on i2c transfer failure.
[ Upstream commit 96f3a9392799dd0f6472648a7366622ffd0989f3 ]
Currently when i2c transfers fail the error return -EREMOTEIO
is assigned to err but then later overwritten when the tuner
attach call is made. Fix this by returning early with the
error return code -EREMOTEIO on i2c transfer failure errors.
If the transfer fails, an uninitialized value will be read from b2.
Addresses-Coverity: ("Unused value")
