ravb: Add missing free_irq() call to ravb_close()
BugLink: https://bugs.launchpad.net/bugs/1878232 commit 7fa816b9 upstream. 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.
