vfio/pds: replace bitmap_free with vfree

Browse Source 
[ Upstream commit acb59a4bb8ed34e738a4c3463127bf3f6b5e11a9 ]

host_seq_bmp is allocated with vzalloc but is currently freed with
bitmap_free, which uses kfree internally. This mismach prevents the
resource from being released properly and may result in memory leaks
or other issues.

Fix this by freeing host_seq_bmp with vfree to match the vzalloc
allocation.
