[PATCH] Bluetooth: btmtk: use bool for first_block

[Miles Krause via B4 Relay <devnull+mileskrause5200.gmail.com@kernel.org>]

From: Miles Krause <mileskrause5200@gmail.com>

first_block is reset for each firmware section and is never used outside
the section loop. Declare it as a bool inside the loop to limit its scope
and make its two-state purpose explicit.

No functional change.

Compile-tested on x86_64 with:

  make O=out allmodconfig
  make O=out W=1 drivers/bluetooth/btmtk.o

Sparse-tested with:

  make O=out-sparse allmodconfig
  make O=out-sparse C=1 CHECK=sparse drivers/bluetooth/btmtk.o
