Bug #52983 innodb_(buffer_pool_pages_total|buffer_pool_pages_misc) units have gone wrong

Description:
This part of the multiple buffer pool patch has got it wrong:

-       export_vars.innodb_buffer_pool_pages_total = buf_pool->curr_size;
+       export_vars.innodb_buffer_pool_pages_total = buf_pool_get_curr_size();

-       export_vars.innodb_buffer_pool_pages_misc = buf_pool->curr_size
-               - UT_LIST_GET_LEN(buf_pool->LRU)
-               - UT_LIST_GET_LEN(buf_pool->free);
+       export_vars.innodb_buffer_pool_pages_misc = buf_pool_get_curr_size();

(in srv/srv0srv.c)

buf_pool_get_curr_size() returns the size in bytes, not pages.

innodb_buffer_pool_pages_misc should not be the same as innodb_buffer_pool_pages_total.

How to repeat:
SELECT variable_value FROM information_schema.global_status WHERE LOWER(variable_name) = 'innodb_buffer_pool_pages_total';

The value of innodb_buffer_pool_pages_total
in the information_schema.global_status table
could be computed incorrectly.
