[PATCH 4.17 012/101] ipv6: sr: fix passing wrong flags to crypto_alloc_shash()

[Greg Kroah-Hartman]

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Biggers <ebigg...@google.com>

[ Upstream commit fc9c2029e37c3ae9efc28bf47045e0b87e09660c ]

The 'mask' argument to crypto_alloc_shash() uses the CRYPTO_ALG_* flags,
not 'gfp_t'.  So don't pass GFP_KERNEL to it.

Fixes: bf355b8d2c30 ("ipv6: sr: add core files for SR HMAC support")
