Morduan Zang 220a5ee395 efi/cper: Fix cper_bits_to_str buffer handling and return value 
commit d7f1b4bdc7 upstream.

The return value calculation was incorrect: `return len - buf_size;`
Initially `len = buf_size`, then `len` decreases with each operation.
This results in a negative return value on success.

Fix by returning `buf_size - len` which correctly calculates the actual
number of bytes written.

Fixes: a976d790f4 ("efi/cper: Add a new helper function to print bitmasks")
