This is another set of fixes and improvements to both pblk and lightnvm
core. 

First patch is the leftover from previous patchset, since we decided to
reorganize it a little. Second & third patches are the most crutial, since they
changes the approach to partial read path, so detailed review is needed
especially here.

Other patches are my other findings related to some bugs or potential
improvements, mostly related to some corner cases.

Changes v1 -> v2:
-dropped some not needed patches
-review feedback incorporated for some of the patches
-partial read path changes patch splitted into two patches
