net: phy: Fix truncation of large IRQ numbers in phy_attached_print()
Given NR_IRQS is 2048 on sparc64, and even 32784 on alpha, 3 digits is
not enough to represent interrupt numbers on all architectures. Hence
PHY interrupt numbers may be truncated during printing.
Increase the buffer size from 4 to 8 bytes to fix this.
