octeontx2-pf: fix bitmap leak
The bitmap allocated with bitmap_zalloc() in otx2_probe() was not
released in otx2_remove(). Unbinding and rebinding the driver therefore
triggers a kmemleak warning:
unreferenced object (size 8):
backtrace:
bitmap_zalloc
otx2_probe
Call bitmap_free() in the remove path to fix the leak.
Fixes: efabce290151 ("octeontx2-pf: AF_XDP zero copy receive support")
