fix build failure

Seeing the following in Yocto:

```
09:57:11 | ../git/src/oemcommands.cpp: In function 'ipmi::RspType<std::vector<unsigned char, std::allocator<unsigned char> > > ipmi::ipmiOemQGetDimmInfo(Context::ptr, uint8_t, uint8_t, uint8_t, uint8_t, uint8_t)':
09:57:11 | ../git/src/oemcommands.cpp:1683:31: error: 'findHost' is not a member of 'ipmi::boot'; did you mean 'findHost'?
09:57:11 |  1683 |     auto hostId = ipmi::boot::findHost(ctx->hostIdx);
```
