perf probe: Do not use map_load filters for function
It is simpler to just do the loop, no need for globals and the last user
of such facility disappears.
Testing:
# perf probe -F [a-z]*recvmsg
aead_recvmsg
compat_SyS_recvmsg
compat_sys_recvmsg
hash_recvmsg
inet_recvmsg
kernel_recvmsg
netlink_recvmsg
packet_recvmsg
ping_recvmsg
raw_recvmsg
rawv6_recvmsg
rng_recvmsg
security_socket_recvmsg
selinux_socket_recvmsg
skcipher_recvmsg
sock_common_recvmsg
sock_no_recvmsg
sock_recvmsg
sys_recvmsg
tcp_recvmsg
udp_recvmsg
udpv6_recvmsg
unix_dgram_recvmsg
unix_seqpacket_recvmsg
unix_stream_recvmsg
#
Without filters:
# perf probe -F | tail -5
zswap_pool_create
zswap_pool_current
zswap_update_total_size
zswap_writeback_entry
zswap_zpool_param_set
#
# perf probe -F | wc -l
