IB/rxe: don't crash, if allocation of crc algorithm failed
Following crash happens, if crc algorithm couldn't be allocated:
[ 1087.989072] rdma_rxe: loaded
[ 1097.855397] PCLMULQDQ-NI instructions are not detected.
[ 1097.901220] rdma_rxe: failed to allocate crc algorithmi err:-2
[ 1097.901248] BUG: unable to handle kernel
[ 1097.901249] NULL pointer dereference
[ 1097.901250] at 0000000000000046
[...]
Reason is that rxe->tfm is assigned the error return, which will then
be used for crypto_free_shash() in rxe_cleanup. Fix by using a
temporary variable and assigning it rxe->tfm after allocation succeeded.
Fixes: cee2688e3cd6 ("IB/rxe: Offload CRC calculation when possible")
