[PATCH v3] staging: rtl8723bs: define EEPROM_DEFAULT_DIFF as -2 directly

[Ivy Lopez]

EEPROM_DEFAULT_DIFF is defined as the bare integer literal 0xFE
(254) but is only ever assigned into s8 (signed char) fields used
to store signed TX power calibration offsets. The value -2 is the
intended default offset; expressing it as -2 directly instead of
0xFE avoids relying on implicit truncation of an unsigned-looking
hex literal into a signed field.

No functional change.

v2: express the value as -2 directly instead of casting 0xFE to s8,
    per Dan Carpenter's suggestion
v3: rebase against staging-testing
