[PATCH] Do not clear the value of st_dev in File I/O's stat()

["Julio Guerra" <julio@farjump.io>]

Do not clear the value of st_dev in the fileio stat structure sent to the
target. It prevents from being able to check the file type on the target.
Note that the fileio function fstat `remote_fileio_func_fstat()` doesn't clear
this field.

	* remote-fileio.c: do not clear the value of st_dev in File I/O's stat().
