EDAC, mce_amd: Don't emit 'CE' for Deferred error

Currently, when decoding an MCE, we display 'CE' for a Deferred error, like
this:

[Hardware Error]: CPU:0 (15:2:0) MC4_STATUS[Over|CE|MiscV|-|AddrV|Deferred|-|UECC]: 0xdc04b00095080813

When the 'UC' bit in the MCx_STATUS register is clear, the error status
is either a Corrected error or Deferred error as determined by the
'Deferred' bit. So do not print 'CE' on a deferred error.

Refer to AMD Error Scope Hierarchy table in a newer BKDG (example:
49125_15h_Models_30h-3Fh_BKDG.pdf, section "RAS Features").
