Chen Yu 2961b331b0 ACPI: tools: pfrut: Check if the input of level and type is in the right numeric range

[ Upstream commit 0bc23d8b2237a104d7f8379d687aa4cb82e2968b ]

The user provides arbitrary non-numeic value to level and type,
which could bring unexpected behavior. In this case the expected
behavior would be to throw an error.

 pfrut -h
usage: pfrut [OPTIONS]
code injection:
-l, --load
-s, --stage
-a, --activate
-u, --update [stage and activate]
-q, --query
-d, --revid
update telemetry:
-G, --getloginfo
-T, --type(0:execution, 1:history)
-L, --level(0, 1, 2, 4)
-R, --read
-D, --revid log

 pfrut -T A
 pfrut -G
log_level:0
log_type:0
log_revid:2
max_data_size:65536
chunk1_size:0
chunk2_size:1530
rollover_cnt:0
reset_cnt:17

Fix this by restricting the input to be in the expected range.
