[PATCH] nvme: Use __func__ macro in place of function name

[John Pittman]

Function nvme_keep_alive_end_io() refers to itself in in a call
to dev_err().  It does so using the actual function name in the
error message.  This should be replaced by a call to the __func__
macro.  Using the macro will prevent future potential risk of
the function name changing and failure to change the associated
error message.  This issue was exposed by checkpatch.pl.
