[Qemu-block] [PATCH 1/7] block: fix comment for bdrv_get_allocated_file_size()

[Vladimir Sementsov-Ogievskiy]

Current comment is not clear enough: which sparseness is meant, coming
from sparse image format or from sparse file system?

For example, if we have qcow2 above raw file on non-sparse file system,
this function will say nothing about unallocated (by qcow2 layer)
clusters.
