dm-bufio: clean-up cache size reading

In the original dm-bufio, setting dm_bufio_cache_size to 0 meant to set
the default value. However, when the code was refactored in the commit
450e8dee51aa, the meaning of 0 is inconsistent, at some places, we just
read the variable dm_bufio_cache_size without testing it to zero.

This commit cleans up the zero handling, all reads of dm_bufio_cache_size
go through the function dm_budio_get_cache_size() and this function tests
the variable for zero and sets the default cache size in this case.
