Crash when calling ONLP's SFP API from openolt agent

[saswat108]

Hello Team,

While trying to use the ONLP's SFP API in openolt agent, I am encountering this error:

"Assignment of different size bitmaps
Aborted"

This is the sequence of function calls my function in openolt agent is making:

onlp_sfp_bitmap_t bitmap;
onlp_sfp_bitmap_t_init(&bitmap);
onlp_sfp_bitmap_get(&bitmap); ==> aborts here

I also see a coredump with the following backtrace:

#0 0x00007ffff5f6bc83 in aim_bitmap_get () from /lib/x86_64-linux-gnu/libonlp.so.1

Do you call onlp_init() before using other onlp APIs?
There is an application that uses onlp APIs. FYI. https://github.com/opencomputeproject/OpenNetworkLinux/blob/master/packages/base/any/onlp/src/onlp/module/src/onlp_main.c

Thanks, Lewis-Kang!
Adding onlp_init() resolved the issue.
