net: stmmac: xgmac: fix a typo of register name in DPP safety handling

Browse Source 
commit 1ce2654d87 upstream.

DDPP is copied from Synopsys Data book:

DDPP: Disable Data path Parity Protection.
    When it is 0x0, Data path Parity Protection is enabled.
    When it is 0x1, Data path Parity Protection is disabled.

The macro name should be XGMAC_DPP_DISABLE.

Fixes: 46eba193d0 ("net: stmmac: xgmac: fix handling of DPP safety error for DMA channels")
