net/bnxt: avoid unnecessary endianness conversion

[ upstream commit 8599820 ]

The "active_fec_signal_mode" in HWRM_PORT_PHY_QCFG response is uint8_t.
So no need of endianness conversion while parsing response.
Also, signal_mode is the first 4bits of "active_fec_signal_mode".

Fixes: c23f9de ("net/bnxt: support 200G PAM4 link")
