[PATCH 1/1] cxl/mem: Fix for the index of Clear Event Record Handle

[Yuquan Wang]

The dev_dbg info for Clear Event Records mailbox command would report
the handle of the next record to clear not the current one.

This was because the index 'i' had incremented before printing the
current handle value.

This fix also adjusts the index variable name from 'i' to 'clear_cnt'
which can be easier for developers to distinguish and understand.
