nvmecontrol: Make the error log page work on native format
As the number of page types proliferates, it becomes untennable to convert them in read_logpage (especailly since new UUID page types will need to be supported). Convert the error page printing code to operate on little endian data. Sponsored by: Netflix Reviewed by: chuck Differential Revision: https://reviews.freebsd.org/D44680
