mkfs.xfs: Assign proper defaults to rmapbt and reflink flags
The "defaultval" field in the options structure was a bit confusing,
so when the rmapbt & reflink options got added, the desire was
to keep them off by default, and "defaultval = 0" got set.
However, the purpose of this field is to define the default value
when the flag is specified with no associated value, i.e.
-m rmapbt vs. -m rmapbt=0 or -m rmapbt=1
Today, the resulting behavior is unexpected, and different from any
other mkfs flags; specifying "-m rmapbt,reflink" results in a
filesystem /without/ those features.
Fix these to be consistent with every other boolean flag in the
mkfs options, so that specifying the flag with no value will
enable the feature.
