Subject: [PATCH v1] Remove redundant HandleWalWriterInterrupts().

Because of commit 1bdd54e662, the code of HandleWalWriterInterrupts()
became the same as HandleMainLoopInterrupts(). So this commit removes
HandleWalWriterInterrupts() and makes walwriter use
HandleMainLoopInterrupts() for improved code simplicity.
