fsx: remove XFS_IOC_ALLOCSP operation entirely

Due to XFS_IOC_ALLOCSP is nearly retired from linux xfs, and the
ALLOCSP testing in fsx easily trigger errors. So compare with
disable it by default, I'd like to remove it entirely. So this patch
revert two patches:

cd99a499 ("fsx: disable allocsp_calls if -F is specified")
a32fb1bb ("fsx: add support for XFS_IOC_ALLOCSP")
