[PATCH] mm-modem-mbm.c: add *E2NAP regexp to catch messages with error codes

[Torgny Johansson <torgny johansson ericsson com>]

Hi!

The following patch adds a new regular expression to be able to catch e2nap unsolicited messages containg an error code e.g. *E2NAP: 0,36. 
Without it, you could get weird responses for "get_imsi" etc where the E2NAP unsolicited message would be included in the response.

Regards
