[PATCH v2025.09.y 44/58] virtio: fix variable shadowing in virtqueue_add_sgs input scatter loop

[Ahmad Fatoum]

The inner for loop in the in_sgs processing section had a local
declaration 'struct scatterlist *sg = sgs[n]' that shadowed the loop
variable 'sg' from the enclosing for statement.

Remove the shadowing declaration so the loop variable is used
consistently, matching the out_sgs loop.
This aligns the loop with the logic above for out_sgs.

(cherry picked from commit 2731cfdb8dcc449b96b5829a2947866a5c6b19eb)
