bnxt_re: fix assertion in bnxt_re_alloc_page

[ Upstream commit 7113c9e ]

When using libibverbs with a BCM57508 NIC and the bnxt_re driver, an
assertion in _ioctl_next_attr fails. The issue traces back to an
incorrect parameter count passed to DECLARE_COMMAND_BUFFER in
bnxt_re_alloc_page. Set the parameter count to the correct value to
prevent the assertion.
