Roman Smirnov 05fb2bf477 udf: prevent integer overflow in udf_bitmap_free_blocks() 
[ Upstream commit 56e69e59751d20993f243fb7dd6991c4e522424c ]

An overflow may occur if the function is called with the last
block and an offset greater than zero. It is necessary to add
a check to avoid this.

Found by Linux Verification Center (linuxtesting.org) with Svace.

[JK: Make test cover also unalloc table freeing]
