Log Message:
nfs: Avoid UB in integer shift amounts.

Just use ilog2 explicitly here, instead of writing out a loop with
shifts and increments to compute it more slowly and buggily.  Note
the confusing fencepost adjustment.  Clamp _PC_FILESIZEBITS at the
actual size of off_t since we can't go beyond that.
