Fix trim-related issues

Fixes:
* Use uint64 instead of off_t when handling offset and size
  of the trimmed range in the fs_trim_data structure
* BlockAllocator::Trim: Correct the size of a buffer
* ram_disk, mmc: Do not trim past device capacity

Improvements:
* BlockAllocator::Trim: Because the received offset and size
  are ignored by BFS (the functionality is not implemented yet),
  return B_UNSUPPORTED if the range does not cover the whole
  partition
* ram_disk, mmc: More accurate calculation of the number
  of trimmed bytes
* devfs: Add a uint64 version of translate_partition_access()
