MLK-18675-09 brcmfmac: enlarge buffer size of caps to 512 bytes
The buffer size of return of cap iovar is greater than 256 bytes in
some firmares. For instance, the return size of cap iovar is 271 bytes
in 4373 13.10.246.79 firmare. It makes caps buffer is default value and
cause the feature capability parsing failed.
Because of that, we enlarge caps buffer size to 512 bytes and add
the error print for cap iovar error.
