mce-amd-smca: update smca_hwid to use smca_bank_types
bank_type is used as smca_bank_types everywhere, there's no point in
declaring it as unsigned int. It also upsets covscan:
3. rasdaemon-0.6.7/mce-amd-smca.c:914: assignment: Assigning: "bank_type" = "s_hwid->bank_type".
7. rasdaemon-0.6.7/mce-amd-smca.c:926: cond_at_most: Checking "bank_type >= 64U" implies that "bank_type" and "s_hwid->bank_type" may be up to 63 on the false branch.
14. rasdaemon-0.6.7/mce-amd-smca.c:942: overrun-local: Overrunning array "smca_mce_descs" of 38 16-byte elements at element index 63 (byte offset 1023) using index "bank_type" (which evaluates to 63).
# 940| /* Only print the descriptor of valid extended error code */
# 941| if (xec < smca_mce_descs[bank_type].num_descs)
# 942|-> mce_snprintf(e->mcastatus_msg,
# 943| "%s. Ext Err Code: %d",
# 944| smca_mce_descs[bank_type].descs[xec],
