Subject: [PATCH v3 2/2] mm: swap.h: Remove deleted field from comments
The comment for struct swap_info_struct.lock incorrectly mentions fields
that have already been deleted from the structure.
Updates the comments to accurately reflect the current struct
swap_info_struct.
There is no functional change.
