net/mlx5: Read embedded cpu after init bit cleared

Browse Source 
[ Upstream commit bbfa4b58997e3d38ba629c9f6fc0bd1c163aaf43 ]

During driver load it reads embedded_cpu bit from initialization
segment, but the initialization segment is readable only after
initialization bit is cleared.

Move the call to mlx5_read_embedded_cpu() right after initialization bit
cleared.
