[PATCH v3 3/6] staging: rtl8723bs: use u8 for frame types in rtw_security.c

[Pranav Desai]

Replace 'uint' with 'u8' for the 'frtype' and 'frsubtype' variables
in rtw_security.c.

These variables are populated by the GetFrameType() and GetFrameSubType()
macros, which read a 16-bit value but apply a bitwise mask (bits 2-3 for
type, bits 2-7 for subtype). Because the highest possible value after
masking is 252, these variables are guaranteed to fit within an 8-bit
unsigned integer.
