ee37391e97 Fix discard request map allocation 
Discard handling splits large request into several steps.
However the actual size of request map for discard was
determined based on original request size, not step request
size, resulting in waste of memory and allocations > 4K.

fits into one page (4K) regardless of cacheline size.

d9c987e068 Flush metadata after changing status of each sector 
In case of cleaning metadata used to be flushed only when status of whole cache
line changed to clean.

This patch ensures that metadata flush is triggered after changin status of each
single sector is cache line.

2f10365086 Flush metadata after setting dirty status of each sector. 
After second dirty write to cache line which was already dirty, metadata flush
was not triggered. In case of dirty shutdown, this led to data corruption.

ecbb5cbc1b Make RAM infinite in POSIX env 
Since the calculation that's being used right now isn't too acurate
anyways, let's just get rid of it, maybe we'll find more memory-related
bugs.

65756a8160 Moved setting ctx for temporary cache object before metadata init 
This way debug prints during metadata init phase won't cause crash
(because of the fact that temporary cache object does not have proper
ctx set hence does not have logger obj).
