Fix file descriptor checking

'0' is also a valid file descriptor so this commit fixes incorrect
checks on fd after opening a file. Actually, fd 0, 1 and 2 will be
assigned to stdin, stdout and stderr respectively so this patch
doesn't fix any issue but it's for code consistency.

Tested: Detecting and reading sensors worked well.
