[PATCH -next] nvdimm/btt: Fix btt_init() kernel-doc comment

[Yang Li <yang.lee@linux.alibaba.com>]

Add the description of @nd_region and remove @maxlane in
btt_init() kernel-doc comment to remove warnings found
by running scripts/kernel-doc, which is caused by using 'make W=1'.
drivers/nvdimm/btt.c:1584: warning: Function parameter or member
'nd_region' not described in 'btt_init'
drivers/nvdimm/btt.c:1584: warning: Excess function parameter 'maxlane'
description in 'btt_init'
