Igor Konopko 2c4d5356e6 lightnvm: pblk: do not overwrite ppa list with meta list 
Ehen using pblk with 0 sized metadata both ppa list and meta list
points to the same memory since pblk_dma_meta_size() returns 0 in
that case.

This patch fix that issue by ensuring that pblk_dma_meta_size()
always returns space equal to sizeof(struct pblk_sec_meta) and thus
ppa list and meta list points to different memory address.

Even that in that case drive does not really care about meta_list
pointer, this is the easiest way to fix that issue without introducing
changes in many places in the code just for 0 sized metadata case.

The same approach needs to be also done for pblk_get_sec_meta()
since we also cannot point to the same memory address in meta buffer
when we are using it for pblk recovery process
