[GIT PULL 06/19] lightnvm: enable nvme size compile asserts
From: Matias BjÃrling
Date: Sat Apr 15 2017 - 15:00:41 EST
The asserts in _nvme_nvm_check_size are not compiled due to the function
not begin called. Make sure that it is called, and also fix the wrong
sizes of asserts for nvme_nvm_addr_format, and nvme_nvm_bb_tbl, which
checked for number of bits instead of bytes.
