[PATCH v2 1/3] nvme-hwmon: Return error on kzalloc failure

[Serge Semin <Sergey.Semin@baikalelectronics.ru>]

Inability to allocate a buffer is a critical error which shouldn't be
tolerated since most likely the rest of the driver won't work correctly.
Thus instead of returning the zero status let's return the -ENOMEM error
if the nvme_hwmon_data structure instance couldn't be created.
