ubiattach: introduce disable_fm in UBI_IOCATT
The ioctl UBI_IOCATT has been extended with disable_fm parameter after
[1].
This parameter is used for disabling fastmap for target ubi device.
If 'disable_fm' is set, ubi doesn't create new fastmap even the module
param 'fm_autoconvert' is set, and existed old fastmap will be destroyed
after attaching process.
A simple test case in [2].
