CLM doesn't check that dimensionality is correct for anything it reads in via ncdio_pio

CLM's use of reading of netCDF files via PIO in ncdio_pio, rarely checks if the dimensions are correct for variables being read in. This is notably true of the global reads in for the PFT parameter fields. The lack of error checking caused us to spend a bunch of time chasing down an error that was simply due to the size of a field on a netCDF file to be smaller than expected.
