bnx2: Fix compiler warning in bnx2_disable_forced_2g5().

drivers/net/bnx2.c: In function 'bnx2_disable_forced_2g5':
drivers/net/bnx2.c:1489: warning: 'bmcr' may be used uninitialized in this function

We fix it by checking return values from all bnx2_read_phy() and proceeding
to do read-modify-write only if the read operation is successful.

The related bnx2_enable_forced_2g5() is also fixed the same way.
