[PATCH -next] libnvdimm: Fix some kernel-doc comments

[Yang Li]

Make the description of @nvdimm to @ndd in function
nvdimm_init_nsarea() and nvdimm_allocated_dpa () to silence the warnings:
drivers/nvdimm/dimm_devs.c:59: warning: Function parameter or member 'ndd' not described in 'nvdimm_init_nsarea'
drivers/nvdimm/dimm_devs.c:59: warning: Excess function parameter 'nvdimm' description in 'nvdimm_init_nsarea'
drivers/nvdimm/dimm_devs.c:844: warning: Function parameter or member 'ndd' not described in 'nvdimm_allocated_dpa'
drivers/nvdimm/dimm_devs.c:844: warning: Excess function parameter 'nvdimm' description in 'nvdimm_allocated_dpa
