LU-6245 server: remove types abstraction from quota/target/nodemap code

Originally when lustre code was built for userland we needed
a proper way to handle 32 bit and 64 bit platforms when
reporting unsigned longs. Now that this code is only built
for kernel space and the kernel has it own special string
handling functions we don't need this abstraction anymore.
Remove this abstraction from the quota/target/nodemap code.
