====================
ibmvnic: Fix bugs and memory leaks

This is a small patch series fixing up some bugs and memory leaks
in the ibmvnic driver. The first fix frees up previously allocated
memory that should be freed in case of an error. The second fixes
a reset case that was failing due to TX/RX queue IRQ's being
erroneously disabled without being enabled again. The final patch
fixes incorrect reallocated of statistics buffers during a device
reset, resulting in loss of statistics information and a memory leak.
