bcma: fix buffer size caused crash in bcma_core_mips_print_irq()
Used buffer wasn't big enough to hold whole strings. Example output of
this function is:
[ 0.180892] bcma: bus0: core 0x0800, irq: 2(S)* 3 4 5 6 D I
[ 0.180948] bcma: bus0: core 0x0812, irq: 2(S) 3* 4 5 6 D I
[ 0.180998] bcma: bus0: core 0x082d, irq: 2(S) 3 4* 5 6 D I
[ 0.181046] bcma: bus0: core 0x082c, irq: 2(S) 3 4 5 6 D I*
which means we need to store up to 24 chars.
