bnxt_en: Fix possible memory leak in bnxt_rdma_aux_device_init()

[ Upstream commit 7ac10c7d728d75bc9daaa8fade3c7a3273b9a9ff ]

If ulp = kzalloc() fails, the allocated edev will leak because it is
not properly assigned and the cleanup path will not be able to free it.
Fix it by assigning it properly immediately after allocation.
