Revert "posix: device_io: implement fileno()"

This reverts commit 48dff55. PR zephyrproject-rtos#73978 introduced a regression. Unfortunately this PR cannot be reverted without reverting also Let's revert both PRs to stabilize main again towards the 3.7 release. For more details on the issue see zephyrproject-rtos#75205 Signed-off-by: Alberto Escolar Piedras <[email protected]>
