Lars-Peter Clausen 1f1cc4566b gpio: GPIO_GET_CHIPINFO_IOCTL: Fix line offset validation 
The current line offset validation is off by one. Depending on the data
stored behind the descs array this can either cause undefined behavior or
disclose arbitrary, potentially sensitive, memory to the issuing userspace
application.

Make sure that offset is within the bounds of the desc array.
