libmtd: don't print an error message for devices without ecc support
The libmtd library tries to obtain the available OOB size via the sysfs
with a fallback to the ECCGETLAYOUT ioctl. For some devices (e.g. plat-ram),
the fallback path is always taken and prints an error message to stderr
since the ioctl fails.
This patch fixes the fallback path by suppressing the error message if
errno is set to EOPNOTSUPP (i.e. the device simply doesn't support that).
Fixes: a10353584f93 ("libmtd: Add support to access OOB available size")
