[PATCH v3 4/6] staging: rtl8723bs: use explicit types for math variables and iterators

[Pranav Desai]

Replace 'uint' with explicit types for variables used in math operations
and loops inside the aes_cipher() and aes_decipher() functions:

- Change 'payload_remainder' to u8 because it is calculated as (plen % 16),
which guarantees a range of 0-15.
- Change 'payload_index' to u32 because it indexes into the payload, which
is bounded by plen (u32).
- Change 'num_blocks' to u32 since it is derived from 'plen' (u32).
- Change loop iterators (i, j) to standard 'unsigned int'.
