(Same change as #4940, adding to the 6.0 branch)
In DatabaseDescriptor:1132, the exception states: compressed_read_ahead_buffer_size must be at least 256KiB (set to 0 to disable). But, if an operator ever later tries to disable the buffer by following this message and setting sizeInKb to 0, setCompressedReadAheadBufferSizeInKb() will throw an error that sizeInKb < 256.
This PR explicitly allows a value of 0 in setCompressedReadAheadBufferSizeInKb (I’ve traced that 0 is handled in every other place that reads this value).
