bme280 github code user_i2c_read have bugs

[Barrypp_zzx]

in https://github.com/BoschSensortec/BME280_driver/blob/master/examples/linux_userspace.c

user_i2c_read function didn't check the return of read function. If bme280 disconnected unexpected, user_i2c_read will not report any error, then subsequent code may give wrong data.

Hi Barrypp_zzx,

Thank for your feedback. You could modify the reference code and adapt it to your software project.

[Barrypp_zzx]

Ok. But you will correct the code on GitHub, right ?

[BSTRobin]

Yes, Barrypp_zzx. We will update Github code.
