[PATCHv2 2/7] nvme: use table_get_value_width() in table_print_centered()

[Nilay Shroff <nilay@linux.ibm.com>]

table_print_centered() open-codes the logic to determine the width of a
table value, even though a helper already exists for this purpose.

Replace the open-coded width calculation with a call to
table_get_value_width() to avoid duplication and keep the behavior
consistent across the table helpers. Also, ensure that
table_get_value_width() returns -1 on failure so the caller could
then handle error as needed.
