net/mlx5: fix unintentional sign extension on shift of dest_attr->vport.vhca_id
Shifting dest_attr->vport.vhca_id << 16 results in a promotion from an
unsigned 16 bit integer to a 32 bit signed integer, this is then sign
extended to a 64 bit unsigned long on 64 bitarchitectures. If vhca_id is
greater than 0x7fff then this leads to a sign extended result where all
the upper 32 bits of idx are set to 1. Fix this by casting vhca_id
to the same type as idx before performing the shift.
