Fix unused variable warning in ipsec_mbuf.c
With clang 15, the following -Werror warning is produced:
sys/netipsec/ipsec_mbuf.c:93:24: error: variable 'alloc' set but not used [-Werror,-Wunused-but-set-variable]
int todo, len, done, alloc;
^
The 'alloc' variable appears to have been a debugging aid that has never
been used for anything, so remove it.
