[Bug] Fix the calculation of the variable "left_bytes" in data_dir.cpp
(#4609)
Suppose that the current available byte in a disk is `_available_bytes`.
After the data with size of `incoming_data_size` is written in the disk, the
left space in the disk should be calculated as follow :
`int64_t left_bytes = _available_bytes - incoming_data_size;`
rather than:
`int64_t left_bytes = _disk_capacity_bytes - _available_bytes -
incoming_data_size;`
