[ISDN]: fix section mismatch warning in enpci_card_msg

Fix following warnings:
WARNING: drivers/isdn/hisax/built-in.o(.text+0x3cf50): Section mismatch in reference from the function enpci_card_msg() to the function .devinit.text:Amd7930_init()
WARNING: drivers/isdn/hisax/built-in.o(.text+0x3cf85): Section mismatch in reference from the function enpci_card_msg() to the function .devinit.text:Amd7930_init()

enpci_card_msg() can be called outside __devinit context
referenced function should not be annotated __devinit.

Remove annotation of Amd7930_init to fix this.
