ravb: Add missing free_irq() call to ravb_close()
When reopening the network device on ra7795/salvator-x, e.g. after a
DHCP timeout:
IP-Config: Reopening network devices...
genirq: Flags mismatch irq 139. 00000000 (eth0:ch24:emac) vs. 00000000 (eth0:ch24:emac)
ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch24:emac
IP-Config: Failed to open eth0
IP-Config: No network devices available
The "mismatch" is due to requesting an IRQ that is already in use,
while IRQF_PROBE_SHARED wasn't set.
However, the real cause is that ravb_close() doesn't release the R-Car
Gen3-specific secondary IRQ.
Add the missing free_irq() call to fix this.
