base-sim: fix length when reading GID1/GID2
We were attempting to read 15 bytes unconditionally, regardless of the
size of the EF_gid1 and EF_gid2 files.
This operation would succeed in some SIM cards even if the actual file
lengths are shorter:
AT+CRSM=176,28478,0,0,15
+CRSM: 144,0,"FFFF"
OK
But the operation would fail in some other SIM cards due to the length
mismatch:
AT+CRSM=176,28478,0,0,15
+CRSM: 103,0
OK
Using 0 as requested length instructs the modem to read the length
specified in the EF status information, which is also the same
approach we do in QMI and MBIM.
AT+CRSM=176,28478,0,0,0
+CRSM: 144,0,"FFFF"
OK
