cephfs: Fix cephfs PVC sizing

Browse Source 
Issue:
The RoundOffCephFSVolSize() function omits the fractional
part when calculating the size for cephfs volumes, leading
to the created volume capacity to be lesser than the requested
volume capacity.

Fix:
Consider the fractional part during the size calculation so the
rounded off volume size will be greater than or equal to the
requested volume size.
