[PATCH 1/4] fs: fat: propagate actual error code when opening/creating files

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We currently map all error codes to -EINVAL when opening or creating a
file, when the underlying functions are capable of returning more error
codes like -EISDIR or -EROFS.

Propagate the received error code to tell consumers more about what went
wrong.
