[ Upstream commit 713baf3dae8f45dc8ada4ed2f5fdcbf94a5c274d ]
An earlier commit replaced using batostr to using %pMR sprintf for the
construction of session->name. Static analysis detected that this new
method can use a total of 21 characters (including the trailing '\0')
so we need to increase the BTNAMSIZ from 18 to 21 to fix potential
buffer overflows.
Addresses-Coverity: ("Out-of-bounds write")
Fixes: fcb73338ed53 ("Bluetooth: Use %pMR in sprintf/seq_printf instead of batostr")
