Always cancel read cell on write path

[akiradeveloper]

Cancelling possible read cache on only write-miss may be okay but it is very difficult for me to reason the correctness.

Always cancelling doesn't harm the performance so much because write-hit is not often and the lookup overhead is small enough.

For these reasons, I do this change.

Pull Request Overview

This PR modifies the write path logic to always cancel read cache cells, regardless of whether a write operation results in a cache hit or miss. Previously, the might_cancel_read_cache_cell() function was only called when the cache lookup resulted in a miss (else clause), but now it executes unconditionally after cache lookup operations.

• Removes conditional execution of read cache cell cancellation in write operations
• Applies the change to both do_process_write and process_write_wa functions
• Simplifies the logic by making read cache cancellation consistent across all write scenarios

[nitpick] There appears to be an unnecessary blank line removal after cache_lookup. This formatting change is unrelated to the core logic change and could be kept for better code readability.
