locking/atomic, riscv: Fix atomic64_sub_if_positive() offset argument
Presently the riscv implementation of atomic64_sub_if_positive() takes
a 32-bit offset value rather than a 64-bit offset value as it should do.
Thus, if called with a 64-bit offset, the value will be unexpectedly
truncated to 32 bits.
Fix this by taking the offset as a long rather than an int.
