#7279: ioctl FIONREAD should set errno to ENOTTY for non supported file

Comment (by korli):
I would add a check for FIONREAD op in
src/system/kernel/fs/fd.cpp:fd_ioctl()
For FDTYPE_FILE, FDTYPE_DIR, FDTYPE_ATTR_DIR, FDTYPE_ATTR values of
descriptor->type, it would return ENOTTY. There is no B_* error mapped to
ENOTTY at the moment.
I'm wondering why it returns B_NOT_SUPPORTED (EOPNOTSUPP) instead of
ENOTTY which is recommended by the
[http://pubs.opengroup.org/onlinepubs/009695399/functions/ioctl.html
spec].
