raw-posix: Fix .bdrv_co_get_block_status() for unaligned image size
Image files with an unaligned image size have a final hole that starts at EOF, i.e. in the middle of a sector. Currently, *pnum == 0 is returned when checking the status of this sector. In qemu-img, this triggers an assertion failure. In order to fix this, one type for the sector that contains EOF must be found. Treating a hole as data is safe, so this patch rounds the calculated number of data sectors up, so that a partial sector at EOF is treated as a full data sector.
