ionic: fix potential irq name truncation

[ Upstream commit 3eb76e71b16e8ba5277bf97617aef51f5e64dbe4 ]

Address a warning about potential string truncation based on the
string buffer sizes.  We can add some hints to the string format
specifier to set limits on the resulting possible string to
squelch the complaints.
