Subject: [PATCH 1/1] cxl/edac: Fix using wrong repair type to check dram event record

cxl_find_rec_dram() is used to find a DRAM event record based on the
inputted attributes. Different repair_type of the inputted attributes
will check the DRAM event record in different ways.
When EDAC driver is performing a memory rank sparing, it should use
CXL_RANK_SPARING rather than CXL_BANK_SPARING as repair_type for DRAM
event record checking.
