Tom Rix f50232193e iio: scd4x: check return of scd4x_write_and_fetch 
Clang static analysis reports this problem
scd4x.c:474:10: warning: The left operand of '==' is a
  garbage value
  if (val == 0xff) {
      ~~~ ^
val is only set from a successful call to scd4x_write_and_fetch()
So check it's return.
