Subject: [PATCH] radiolib: reapply runtime RX boosted gain on SX126x AGC reset

sx126xResetAGC only restored the gain when the build defined
SX126X_RX_BOOSTED_GAIN, so a gain set at runtime was lost on reset.
Match lr11x0ResetAGC and always reapply. Also pass the gain state from
the LLCC68 wrapper, whose call did not match the helper's signature.
