[PATCH 02/14] nvme-core: don't use switch for only one case use

[Chaitanya Kulkarni]

There is no point in using switch case statement for only one case that
takes about 5 lines.

Remove switch case which only checks for the NVME_CTRL_LIVE state and
use simple if statement that only takes one line.
