nvmet: make ctrl model configurable
This patch adds a new target subsys attribute which allows user to
optionally specify model name which then used in the
nvmet_execute_identify_ctrl() to fill up the nvme_id_ctrl structure.
The default value for the model is set to "Linux" for backward
compatibility.

*Use macro for default model, coding style fixes.
*Use RCU for accessing model in for configfs and in
nvmet_execute_identify_ctrl().
