[VFS/STFS] Fix BlockToOffsetSTFS for non-read_only_format (CON) packages

Browse Source 
Previous code would give wrong results for those types of packages as the block_shift would cancel itself out, moving it to happen afterward let it give the right result though, probably a mistake while reversing it.
(eg. block 0 would give 0xB000, but that's wrong for non-read_only packages as 0xA000 and 0xB000 are reserved for the first hash-table there, fixed code returns the correct 0xC000 offset)

Also changed it to a multiply & renamed it to blocks_per_hash_table to make it more obvious what the purpose is.
