This patch avoids getting an error and aborting when a channel does not have a
specific parameter like 'offset' and the file associated with it is not present.
When none of the files from the device folder does not matches the desired channel's
param function iioutils_get_param_float should return 0.
This change is safe previous to calling the function the parameters are set to
their defaults, 0 in case of 'offset'
