Subject: ixgbevf: remove redundant initialization of variable 'dma'
Patch-mainline: v4.17-rc1
Git-commit: 93a6a37c6982ac39206da2fa05dcf5868049a378
References: bsc#1101674 FATE#325150 FATE#325151

Variable dma is initialized with a value that is never read, later
on it is re-assigned a new value, hence the initialization is redundant
and can be removed.

Cleans up clang warning:
drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c:584:13: warning: Value
stored to 'dma' during its initialization is never read
