net: dsa: mv88e6xxx: fix fid_mask when leaving bridge
The mv88e6xxx_priv_state structure contains an fid_mask, where 1 means
the FID is free to use, 0 means the FID is in use.
This patch fixes the bit clear in mv88e6xxx_leave_bridge() when
assigning a new FID to a port.
Example scenario: I have 7 ports, port 5 is CPU, port 6 is unused (no
PHY). After setting the ports 0, 1 and 2 in bridge br0, and ports 3 and
4 in bridge br1, I have the following fid_mask: 0b111110010110 (0xf96).
Indeed, br0 uses FID 0, and br1 uses FID 3.
After setting nomaster for port 0, I get the wrong fid_mask: 0b10 (0x2).
With this patch we correctly get 0b111110010100 (0xf94), meaning port 0
uses FID 1, br0 uses FID 0, and br1 uses FID 3.
