Currently _scratch_mkfs_sized() checks if requested size for the fs
is below 1G for btrfs and forces the --mixed mkfs option. The 1G size
cut off is too larger where the actual size is 114294784 bytes. The
patch 1/9 fixes the _scratch_mkfs_sized() to check for 114294784
bytes instead. By this now we test the default config (non mixed).
And the mixed option may still be tested using the MKFS_OPTIONS.
This change only affect btrfs FS and test cases using the
_scratch_mkfs_sized() in generic and btrfs.


Also, to make sure btrfs is created in non-mixed mode, so in each individual test cases we need to make sure that _scratch_mkfs_sized()
been requested to create a FS of at least 200mb in size (114294784
bytes rounded off to the nearest 100). And there are few test
cases which does not do that, Patches [2,3,4,8,9]/9 fixes them.
These changes affects all FS as such.

And there are some test cases where we use local
variable as an option for the _scratch_mkfs_sized() is being used
and this local variable is not used anywhere else with in the test
case. So patches [5,6,7]/9 drops the local variable and open codes
it. This is a straight forward change as the fs size is kept same
as in the original.

Further, there are test cases generic/250,252,256 which uses
_scratch_mkfs_sized with < 200mb but its fix isn't straight forward
and they are not yet ready for the review.

The affected testcases (which calls _scratch_mkfs_sized) [1] have
been tested with xfs/ext4 and btrfs. And there are no regressions.
