Ben MeadorsandGitHub 134fe5ec3e Stop BLE log streaming from starving the NimBLE notify pool (#11253) 
sendLog() notified once per firmware log line with no backpressure. With
debug_log_api_enabled and a subscribed client, a logging burst drains the
msys_1 mbuf pool that every GATT notification and ATT response allocates
from, so ble_gatts_notify_custom starts returning BLE_HS_ENOMEM (rc=6) --
for the fromNum doorbell too, not just the log line that exhausted it.
Each failure then prints an error over serial at ~12ms apiece, which is
itself enough to throttle the main loop during a burst.

Register a callback on the log characteristic so the host's own
ERROR_GATT verdict pauses log notifies for 250ms and lets the pool
refill. Keying off the failure rather than a free-block count keeps this
correct however the pools are sized.

Also restore CONFIG_BT_NIMBLE_MSYS_1_BLOCK_COUNT to the IDF default of
12. Pool selection is by block size and a notify request always resolves
to the smallest pool, so msys_1 is the only pool GATT draws from; 8 was
thin once anything chains or fragments. msys_2 and the ACL/EVT transport
pools are left trimmed -- neither is on the notify path, and restoring
the full defaults would re-spend the contiguous allocation that #10741
was fixing on heap-tight boards.

sendLog() also lacked the null check onNowHasData() already has, so a log
line arriving during BLE teardown dereferenced a freed characteristic.

Fixes #11245
