tracing/uprobes: Do not print '0x (null)' when offset is 0
When manually added uprobe point with zero address, 'uprobe_events'
output '(null)' instead of 0x00000000:
# echo p:probe_libc/abs_0 /path/to/lib.bin:0x0 arg1=%ax > \
/sys/kernel/debug/tracing/uprobe_events
# cat /sys/kernel/debug/tracing/uprobe_events
p:probe_libc/abs_0 /path/to/lib.bin:0x (null) arg1=%ax
This patch fixes this behavior:
# cat /sys/kernel/debug/tracing/uprobe_events
p:probe_libc/abs_0 /path/to/lib.bin:0x0000000000000000
