Update LEPTON_SDK.c

[mellbratt]

Had to make these small changes for it to compile on macOS Catalina 10.15.7 and Qt 5.15.2

Hi! Thanks for the PR.

I believe that this change is syntactically correct, but it appears like it will create an infinite recursion at runtime when the function calls itself.

The LEP_GetAttribute function still needs to call the "concrete" implementation of UVC_GetAttribute, defined in src/leptonvariation.cpp, which does the actual communication with the device.

If you provide the compile error message, I might be able to offer a bit more help.

Oops,

Yes I'm new at this. ;D Did as suggested in the error message below and it would then run. Didn't realise it would cause other problems...

EDIT: Tried to fix the line breaks in the error message for clarity
