Gao Xiang 7c3ca1838a erofs: restrict pcluster size limitations ...

Error out if {en,de}encoded size of a pcluster is unsupported:
  Maximum supported encoded size (of a pcluster):  1 MiB
  Maximum supported decoded size (of a pcluster): 12 MiB

Users can still choose to use supported large configurations (e.g.,
for archival purposes), but there may be performance penalties in
low-memory scenarios compared to smaller pclusters.
