Commit e2f3178f0582 ("datapath: Add support for kernel 3.14.") added support for 3.14 kernels and a new OVS_GREP_IFELSE check for the "skg_get_hash" function in the process. "skb_get_hash" was introduced in the Linux kernel commit 3958afa1b272 ("net: Change skb_get_rxhash to skb_get_hash") which exists in >=3.14 but the OVS_GREP_IFELSE macro also matches the "skb_get_hash_raw" function which exists in older kernels. As a result of which, the check makes the build system behave as if the "skb_get_hash" function is available in these older kernels leading to build failures. We fix this by explicitly checking for "skb_get_hash(" which matches the function definition.
