After the NVMe library API change to perform user copies, we don't need
to pass rte_malloc() memory to the NVMe controller utility functions
like spdk_nvme_ctrlr_cmd_get_log_page().
Use regular global variables to simplify the identify example code.
At the same time, fix the code that retrieves error log pages -
previously, it was allocating space for multiple error log entries, but
it was only passing the size of a single entry to the Get Log Page
command. Now we preallocate the worst-case array size: ELPE, which
indicates the maximum number of error log page entries, is a single
byte, and it is 0's based, so the largest possible array is just 256
entries.
