Amit Engel e17016f6dc nvmet: fix per feat data len for get_feature 
The existing implementation for the get_feature admin-cmd does not
use per-feature data len. This patch introduces a new helper function
nvmet_feat_data_len(), which is used to calculate per feature data len.
Right now we only set data len for fid 0x81 (NVME_FEAT_HOST_ID).

Fixes: commit e9061c3978 ("nvmet: Remove the data_len field from the nvmet_req struct")
