gprs_llc: Prevent llme_alloc/lle_init from reading invalid memory
Make the llc_default_params structure from which data is initialized
large enough. Otherwise address sanitizer complains with out-of-bounds
reads.
Only SAPIs 1, 2, 3, 5, 7, 8, 9, 11 are defined for GPRS but the
struct gprs_llc_llme includes NUM_SAPIS lle's and they are populated
from the llc_default_params structure.
