erofs: initialize decompression early

[ Upstream commit fe1e57d44d7f106df9048e815e4862cf63921220 ]

 - Rename erofs_init_managed_cache() to z_erofs_init_super();
 - Move the initialization of managed_pslots into z_erofs_init_super() too;
 - Move z_erofs_init_super() and packed inode preparation upwards, before
   the root inode initialization.

Therefore, the root directory can also be compressible.
